I have done p90x a couple times. in one of its plyometrics workouts it has you jumping for almost an hour and landing controlled and soft. so it is possible to do a hardcore HIIT workout that involves jumping if you control the landing. "like a cat on your toes" is what old Tony says anyways lol.
it makes for a more dificult workout with attention to your landing but worth a try. Also any type of punching, kicking karate/ kick boxing could be used. very qiuit in terms of floor noise.
