Just tried Desktop Session: Plasma (Wayland) on my 22.04 install

Switched from Desktop Session: Plasma (X11) to Plasma (Wayland) at the SDDM Login screen. Not so long story made shorter: As long as Plasma (X11) remains an option, I won't be using Plasma (Wayland) for my Desktop Session.

Under Plasma (Wayland), there is a missing configuration setting in Touchpad (System Settings > Input Devices) that is an ABSOLUTE MUST HAVE for me, and that's the Enable/Disable Touchpad. It includes the setting: Disable touchpad when mouse is plugged in

Package xserver-xorg-input-synaptics gives me that feature, and on my laptop, I always look for and install that package after installing a new Kubuntu.

I don't even have that ability on the X11 Plasma any longer. It is not there under settings. So I've installed touchpad-indicator via a ppa to do it for me. I'm with you however would like to see it added back as an option. Especially the disable touchpad when mouse is plugged in. Touchpad-indicator is only a work around for a feature that used to be native.

Xorg is not disappearing any time soon, and neither will Plasma require it, at least for some time as well.

Anyway. ,The missing disable option is odd. Been using Wayland exclusively on my laptop (Intel) and dual-monitor PC AMD graphics), since at least August.
Won't say it has been painless over the past 6+ months, but other than Latte Dock on the PC being a bear in the early stages, it has been mostly painless on my laptop, with the added bonus of trouble-free and hacky-script-free automatic screen rotation.
I could not tell the difference in gaming via Steam on the PC, either.

As to disabling the touchpad, I definitely have this option on my Ideapad, as well as the option to enable the systray widget to toggle it off and on.

I am on Neon, so the same Plasma, but older kernel.
I wonder what the difference is that might be causing this? I definitely am not using the old synaptic touch pad driver, for sure. I wonder if its presence on your system breaks that, as it doesn't support Wayland at all iirc?. Just hypothesizing.
I'll have ti check in the morning, but the trackpad *may* be disabled automatically by kwin when a mouse has plugged in. I am probably wrong though. Maybe it is just has more modern palm rejection methods? Been a while since I used a mouse on a laptop, so I may be rusty in the memory gas tank.

I tried it once, after I entered my password and hit the enter key it thought about it for a while then went straight back to the login screen. I couldn't be bothered to troubleshoot it and have never tried again since. Not for me...
