Unless you know exactly why you have a strong preference for any of the others, and availability concerns notwithstanding, I'd suggest the Pi CM4 model based on the larger ecosystem surrounding the board.

Good advice, but worth noting the CM4 isn't included and there are a surprising number of CM4 variants now. They only advise one specific model number (104000 - the 4gb ram no onboard storage CM4), clarification on this would be good too.

The advice for the no-storage CM4 is because the modules are designed to work with either onboard eMMC or external SD, but the interface is shared so you have to pick one or the other. If you use an eMMC CM4 the sd card slot would not function, but it should otherwise work. The 8GB ram CM4 would also be fine of course.

(It's possible through a different hardware design to support a secondary, slower sd card interface for an emmc cm4 via the SDHOST peripheral connected to some GPIO pins, but the pi cant boot from it)
