I like the idea of xref-find-extra. For keys we can support both auto-compute 
(use first character) and backend-chosen keys, similar to read-multiple-choice. 
We can even allow users to customize it.

Completing-read is a bad idea, as you said, it’s going to be slow, much slower 
and less pleasant to use. With keys I can just type the binding for 
xref-find-extra and type the key, which would feels just like compound 
keybindings.
