eat and vterm don't have these problems for me — backspace works, less and vi work, haven't tried tig (I use magit). No hard blockers.

I do see a consult-fd in 0.35. But otherwise, you might try changing consult-find-args to point to fd instead of find.

For faster grep, I've been using consult-ripgrep. For me, ripgrep has been faster than ag.
