I've also never seen "buster debug" before, but maybe it exists.
Yes! The debug repositories contain packages compiled with the debug flags enabled, which is tremendously useful if a program is crashing:

In Arch or Alpine the user has to recompile the program locally to get a proper backtrace, which can be a pain.

Thanks, I may roll back and give that another try.
Even Buster alone was not sufficient to get stable operation (for some definition of stable *.) In addition to drivers I had to get firmware directly from a Killer Github project.
