Agree with most of your post rpm except this bit.

It's really not a bad call even 250BB deep, you'd need very specific reads on him to even consider folding this. I think his limp/3bet/5bet shove range is QQ+ and that's being conservative, so it's a call once you've 4bet.

Thinking about how we play the rest of our range QQ-22 we are flatting to setmine though not auto folding QQ/JJ on low boards, suited connectors can be played for implied odds as well. IMO it's fine to be unbalanced and 4bet AA only vs him.
