The SPI based implementation is generally demonstrated in the AdaFruit Shield BSP code.

STM32Cube_FW_L4_V1.14.0\Drivers\BSP\Adafruit_Shield\stm32_adafruit_sd.c

The cards work at a block device level.

The FATFS DISKIO layer then sits on top of the SPI, SDIO or SDMMC layer.

I have an SD/SPI block device driver for STM32L412KB at sd_driver. It has some dependencies on FreeRTOS. You might be able to adapt that.
