Pretty simple preflop spot but i'm not sure what to do.

I flatted the open because UTG seems quite nitty. Only 67 hands on him though. Maybe I should have squeezed myself?

I have 1.5k hands on the squeezer. He has an 8% 3bet, 3.3% vs EP, 6.7 vs MP. 4.2% squeeze i'm not sure how relevant that is considering the sample size?

If he calls with QQ+, AK he needs to be bluffing around 50% of the time for the jam to be profitable. I'm not sure if he is. If we do 4bet is it correct to jam or is 4betting smaller better?
