This is correct behaviour because Wayland is not yet stable in the presence of an Nvidia proprietary driver. We hope to fix that by Ubuntu 24.10.

The original intention was to enable Wayland for hybrid systems:

gdm3 (42.0-1ubuntu7) jammy; urgency=medium

    Default to Xorg but offer Wayland with the gear button on the login

but even that turned out to be unreliable. And added to that there was an uninitialized variable in gdm3(?) we fixed a year or two ago which was also causing the session selection to not follow the udev rules.

So it's all very complicated. Overall we would prefer Nvidia systems DID NOT show a Wayland login option yet, but since you've figured out how to enable it, please be aware of the bug list:
