Good friend of mine edits music a lot on linux with bitwig, he said "it's made by some people who left ableton and it's basically the best there is for glitch rn". It's not foss, but it's a pretty solid daw on linux and supports VSTs and so forth. Hard to say about your interface drivers specifically, but generally drivers (other than nvidia video drivers) "just work" on linux these days. So you can probably just plug it in and use it with pulseaudio (sound system that comes with ubuntu and other popular distros). If you want a really easy pre-setup experience check out https://ubuntustudio.org/ it's ubuntu, but with lots of good audio/video software installed and configured nicely.

Also years ago I edited videos as a film major with kdenlive, and my girlfriend actually does so semi-professionally now. So if you're looking for a foss non-linear video editor it's the least shitty one. (admittably lacking behind DaVinci and premire, but you can run DaVinci on linux it's just not foss...)
