Plugable USB4 dock Linux compatibility, or similar recommended USB4 dock with around 100W PD for the AI 300

Looks like that one should work fine. The key you want to look for is “driver-less” to make sure it doesn’t need that awful displaylink crap. This dock seems to be one such dock. Other things to look for are MST with DSC but they often don’t list that specifically.

I recently got this dock because I need 3 monitors and more USB ports than the one you are getting. Works great!
