Was LinVST among the tools you tried? It works really well for my purchased VSTs.

Saving this comment just in case I ever end up in a similar situation. Very well explained!

I have found that some games that are problematic on Windows actually run better on Linux through Proton. Performance in general can be slightly worse or slightly better depending on the game, but these days it definitely rivals Windows. That said, if you like multiplayer games; those usually do not work well on Linux, especially when they have anticheat. Also, native Linux versions are often broken, the Windows version through Proton usually works better.

Can’t speak to the GoXLR, you might be able to find some info on linuxmusicians.com. I got my Tascam audio interface and my Mooer GE200 working out of the box though (with less latency than on Windows).
