Supuestamente el cubeMX puede generar el proyecto para System Workbench, nunca lo he probado por que prefiero no usar ningún IDE, en lugar de eso uso cmake para compilar y vim como editor.
Con respecto a la documentación concuerdo con que los PDF son escuetos y en ocasiones no puedes extraer información que te ofrezca alguna idea sobre como trabajar con los periféricos.
La mayoría de los ejemplos que encuentras en internet son para las std libs (anteriores al cube).
Pero (aquí el pero) si lees el código fuente de las librerías te darás cuenta de que ahí explican paso a paso como usar los periféricos.
Por ejemplo si quiere saber como usar el ADC en el stm32f1, entra al siguiente directorio (en la ruta donde descomprimiste el stm32cube (para estecaso stm32cubef1)
STM32Cube_FW_F1_V1.3.0/Drivers/STM32F1xx_HAL_Driver/Src
Y abre el archivo stm32f1xx_hal_adc.c y el stm32f1xx_hal_adc_ex.c
Al inicio verás los pasos y funciones a implementar
stm32f1xx_hal_adc.c

*** Configuration of top level parameters related to ADC ***
============================================================
[..]
(#) Enable the ADC interface
(++) As prerequisite, ADC clock must be configured at RCC top level.
Caution: On STM32F1, ADC clock frequency max is 14MHz (refer
to device datasheet).
Therefore, ADC clock prescaler must be configured in
function of ADC clock source frequency to remain below
this maximum frequency.
(++) One clock setting is mandatory:
ADC clock (core clock, also possibly conversion clock).
(+++) Example:
Into HAL_ADC_MspInit() (recommended code location) or with
other device clock parameters configuration:
(+++) RCC_PeriphCLKInitTypeDef PeriphClkInit;
(+++) __ADC1_CLK_ENABLE();
(+++) PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_ADC;
(+++) PeriphClkInit.AdcClockSelection = RCC_ADCPCLK2_DIV2;
(+++) HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit);
(#) ADC pins configuration
(++) Enable the clock for the ADC GPIOs
using macro __HAL_RCC_GPIOx_CLK_ENABLE()
(++) Configure these ADC pins in analog mode
using function HAL_GPIO_Init()
(#) Optionally, in case of usage of ADC with interruptions:
(++) Configure the NVIC for ADC
using function HAL_NVIC_EnableIRQ(ADCx_IRQn)
(++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()
into the function of corresponding ADC interruption vector
ADCx_IRQHandler().
(#) Optionally, in case of usage of DMA:
(++) Configure the DMA (DMA channel, mode normal or circular, ...)
using function HAL_DMA_Init().
(++) Configure the NVIC for DMA
using function HAL_NVIC_EnableIRQ(DMAx_Channelx_IRQn)
(++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()
into the function of corresponding DMA interruption vector
DMAx_Channelx_IRQHandler().
*** Configuration of ADC, groups regular/injected, channels parameters ***
==========================================================================
[..]
(#) Configure the ADC parameters (resolution, data alignment, ...)
and regular group parameters (conversion trigger, sequencer, ...)
using function HAL_ADC_Init().
(#) Configure the channels for regular group parameters (channel number,
channel rank into sequencer, ..., into regular group)
using function HAL_ADC_ConfigChannel().
(#) Optionally, configure the injected group parameters (conversion trigger,
sequencer, ..., of injected group)
and the channels for injected group parameters (channel number,
channel rank into sequencer, ..., into injected group)
using function HAL_ADCEx_InjectedConfigChannel().
(#) Optionally, configure the analog watchdog parameters (channels
monitored, thresholds, ...)
using function HAL_ADC_AnalogWDGConfig().
(#) Optionally, for devices with several ADC instances: configure the
multimode parameters
using function HAL_ADCEx_MultiModeConfigChannel().
*** Execution of ADC conversions ***
====================================
[..]
(#) Optionally, perform an automatic ADC calibration to improve the
conversion accuracy
using function HAL_ADCEx_Calibration_Start().
(#) ADC driver can be used among three modes: polling, interruption,
transfer by DMA.
(++) ADC conversion by polling:
(+++) Activate the ADC peripheral and start conversions
using function HAL_ADC_Start()
(+++) Wait for ADC conversion completion
using function HAL_ADC_PollForConversion()
(or for injected group: HAL_ADCEx_InjectedPollForConversion() )
(+++) Retrieve conversion results
using function HAL_ADC_GetValue()
(or for injected group: HAL_ADCEx_InjectedGetValue() )
(+++) Stop conversion and disable the ADC peripheral
using function HAL_ADC_Stop()
(++) ADC conversion by interruption:
(+++) Activate the ADC peripheral and start conversions
using function HAL_ADC_Start_IT()
(+++) Wait for ADC conversion completion by call of function
HAL_ADC_ConvCpltCallback()
(this function must be implemented in user program)
(or for injected group: HAL_ADCEx_InjectedConvCpltCallback() )
(+++) Retrieve conversion results
using function HAL_ADC_GetValue()
(or for injected group: HAL_ADCEx_InjectedGetValue() )
(+++) Stop conversion and disable the ADC peripheral
using function HAL_ADC_Stop_IT()
(++) ADC conversion with transfer by DMA:
(+++) Activate the ADC peripheral and start conversions
using function HAL_ADC_Start_DMA()
(+++) Wait for ADC conversion completion by call of function
HAL_ADC_ConvCpltCallback() or HAL_ADC_ConvHalfCpltCallback()
(these functions must be implemented in user program)
(+++) Conversion results are automatically transferred by DMA into
destination variable address.
(+++) Stop conversion and disable the ADC peripheral
using function HAL_ADC_Stop_DMA()

with transfer by DMA:
(+++) Activate the ADC peripheral (slave) and start conversions
using function HAL_ADC_Start()
(+++) Activate the ADC peripheral (master) and start conversions
using function HAL_ADCEx_MultiModeStart_DMA()
(+++) Wait for ADC conversion completion by call of function
HAL_ADC_ConvCpltCallback() or HAL_ADC_ConvHalfCpltCallback()
(these functions must be implemented in user program)
(+++) Conversion results are automatically transferred by DMA into
destination variable address.
(+++) Stop conversion and disable the ADC peripheral (master)
using function HAL_ADCEx_MultiModeStop_DMA()
(+++) Stop conversion and disable the ADC peripheral (slave)
using function HAL_ADC_Stop_IT()

(+@) HAL_ADC_LevelOutOfWindowCallback() (callback of analog watchdog)
(+@) HAL_ADC_ConvCpltCallback()
(+@) HAL_ADC_ConvHalfCpltCallback
(+@) HAL_ADCEx_InjectedConvCpltCallback()
*** Deinitialization of ADC ***

(++) ADC clock can be hard reset and disabled at RCC top level.
(++) Hard reset of ADC peripherals
using macro __ADCx_FORCE_RESET(), __ADCx_RELEASE_RESET().

(+++) PeriphClkInit.AdcClockSelection = RCC_ADCPLLCLK2_OFF
(+++) HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit)
