I'd prefer to avoid 'equivalent' in this sense, and if used it should refer to the propositional truncation of the type of equivalences.

If we speak of two types being equivalent, it sounds like equivalence is a proposition. We don't do that for equality. What should we do?

Instead of saying "X and Y are equivalent", we could say "there is an equivalence between X and Y". (We do the same for identifications.) That would avoid talking about propositional truncation here.
That would work and treating them in the same fashion seems ideologically sound.

I agree!
Okay, I've eliminated several uses of the word "equivalent", and reworded its introduction. (I didn't have the energy to remove them all.)
