For example, I might give an enemy a bigger hurtbox than their visual so players never have a "that attack should have hit him!" moment, while giving them a smaller hitbox than their visual so players never have a "That attack shouldn't.habe hit me!" moment.

This is great. I think the terminology definitely helps with abstracting the important elements of real time combat. Wow for example is not a game you'd think of in this respect, but it definitely has hurtboxes - just simple radius checks in practice. But the players complain when they feel off.

Interesting! 🧠++
