I don’t think that the unofficial steamos ports are “hacky” if you mean unstable or bad.

Or you could use cython, which is much easier to integrate with a python project. It is only marginally slower than Rust but a little less safe. Numpy libraries are usually the fast. Numba is a little clunky, but can also speed up code. There’s lots of options to speed up python code.

If you want to just work, just install xubuntu.

I found it to be barely noticeable on edge for Linux. Of course, it depends on your connection speed…

You can stream gamepass on the steamdeck
