Actually, RPi does offer the CM4 in a ton of configurations, for example
This is a CM4 (all have the same CPU) with WiFi/Bluetooth, 8GB of RAM, and no eMMC.
I personally have bought a CM4104032, which has WiFi/BT, 4GB RAM, and 32GB of eMMC. With such tight supply these days, I was pretty happy to find this one.
