But, we have basically zero fold equity against hands we are losing to since they called the 4bet and this was an ideal flop for Q-Q+, and have no reason to try to fold out the rest of his likely range (A-K). And we have very poor equity against his calling range to a shove (~17%).

Definitely check/fold the flop. If you hit an Ace/King on the turn, i check/call my stack in.

This may be a good reason to not 4bet A-K deepstacked since this is an ugly spot this deep. With 100BB though against such a range getting it all in on the flop isn't a mistake - as long as you are putting it in first ofc.
i agree, except a laggy villain can have a wider range, including even like QJs, ATs, 77, etc. i think the logic is that he senses frustration and puts hero on AK or just a random 4bet bluff, and see what happens on the flop.

still i like check folding, but i'm not sure it's better than the other options, except prob overbetting all in.
