Why does `C-h b` show `??` as the command name for my key binding?
Don't bind keys to anonymous functions -- C-hb can't tell you the name of the command, because you didn't name it!

Which key prefix is left for user defined bindings?
Not yet mentioned, I'd like to recommend re-binding one of C-- or M--, since they both serve the same purpose. Then you have an entire key free to use.

Which key prefix is left for user defined bindings?
Just override any key that you don't use. Check what (if anything) is binded to a key with C-h k or install which-key-mode. You could also install something like worf or hydra make more room.
