Questions

Is there a KiCad symbol and footprint for the STM32WB55CCU6?

Yes. The symbol is MCU_ST_STM32WB:STM32WB55CCUx and the footprint Package_DFN_QFN:QFN-48-1EP_7x7mm_P0.5mm_EP5.6x5.6mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STM32WB55CCU6?

UFQFPN-48-EP(7x7), with 49 pins. Its footprint is drawn on this page.

Where is the STM32WB55CCU6 datasheet?

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

Where can I order the STM32WB55CCU6?

JLCPCB lists it as part C911134, with 21 in stock; the sellers' links on this page open their listings.

What can replace the STM32WB55CCU6?

Parts like it in the library: the STM32G431CBU6 by STMicroelectronics, the STM32F401CCU6 by STMicroelectronics, the STM32F411CCU6 by STMicroelectronics and the STM32F411CEU6 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
