Proton generally works better than Wine would, so I doubt that would help. Not sure what's wrong with the audio stuff though, as far as I know that should work.
Videos only work on Linux on SDK3 players, which aren't being widely used yet, and that's only if you're hosting them in specific places. It'd be interesting to see if Dropbox actually works for that though.

You shouldn't. You might need a specific type of graphics card though, GPU passthrough is supposedly pretty picky.
