Questions

Is there a KiCad symbol and footprint for the STM32F103CXTX?

Yes. The symbol is Horizon_ic:STM32F103CxTx and the footprint Horizon_ic:QFP48, both drawn on this page. PCBKit places them on a board for you when you design with it.

Where is the STM32F103CXTX datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

What can replace the STM32F103CXTX?

Parts like it in the library: the STM32L15XCXTX by STMicroelectronics and the STM32L412CXTX by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the STM32F103CXTX?

3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
