Back when I switched to Linux, Nvidia worked much better than AMD cards, but everyone hates them for not providing open source drivers, understandably

In my experience, Nvidia drivers work just fine. They’re just proprietary, and once in a while they release a faulty driver (which you can just roll back ofc). Happened to me a couple of times over the past… 14 years, fuck

You can always check ProtonDB

Source?

Also proprietary and requires a “Gamer License” to host servers for more than 32 users.

Mumble is, and has always been, the king of voice chat apps and is completely FOSS. Also it works a lot better.
