There will always be a certain degree of latency in a virtual machine since it's running at the whims of the host OS rather than having full control of the hardware, however with KVM there are definitely things you can do to mitigate that. If you run into issues, take a look at this section of the Arch wiki which goes over performance tuning your VM for maximum performance. Also, not sure if you're planning to do this, but a passed through GPU would obviously help immensely with mitigating VM overhead.

Spent the morning installing Arch and trying. Installation process was uh, liberating, as someone who hasn't tried Arch before.

Passing through the Thunderbolt interface actually worked perfectly as far as I could tell, though I haven't tested anything particularly extravagant yet.

The bigger issue I've had is that the interface I was hoping to use for Linux - a Focusrite Scarlett 18i20, hasn't been playing ball. Or rather, it did work, initially it worked perfectly in fact, but then it seemed to uh, fall over a bit. I'm not entirely convinced that the issue isn't the interface itself rather than anything with Linux as it seems "iffy" with Windows and macOS as well, will investigate later when I have more free time.
