What do you all think? Feedback on this would be great!
I've never really delved into the science of this, but one of the reasons I avoid hardcore cardio is because I don't want it interfering with leg day performance. With that said, a cut is about maintaining muscle mass, and the body is given the best incentive to do so by lifting heavy.

Personally I would wager that as long as you're able to lift heavy, most muscle mass will remain. But if you tax the CNS heavily and dip in weight, you could see some muscle loss.

But from a pure strength perspective, I see so many powerlifters doing GPP training on off days like sled dragging, etc. Stuff that taxes the legs. It would seem on a cursory level that the CNS is much more able to adapt to short bursts of low intensity work, even if this work does involve the use of some resistance.

Just thinking out loud...
