I just pay them off here. Thought about turning AA into a bluff on the river, but it is too strong. I do not like your flop check here, live poker is best just to bet vs wide limp calling ranges. Probably bet bet check line for 1\3 to 1\2 pot.

Flop won't get raised often enough to deincentivize small cbets. 25%-33% OTF. Then OTT I would (exploitatively) use 33% again to force him into tough spot with many hands. I would use this size with any hands that bet as well. again, I don't think they will attack these bets often enough to merit choosing any other size.

As played OTF, turn I would use 33% pot. He has already shown weakness and is unlikely to have much equity here. You can bet small to get value from very small hands.

As played OTT, call river. I think you see a lot of nutted hands with this line but I also believe that players spazz often enough at this level to call here. Ad helps the decision.

I think checking flop makes alot of sense to keep players range wide, allowing us to reap value from a few hands that may stab/allow weak hands to hit a pair/equity we can then value bet. it also allows us to use a bigger sizing on later streets to get clean value when check too, as when we flop check and then bet turn, alot of live players are going to assume we have nothing because a J or overpair would bet the flop. I think the idea of betting flop and turn is also reasonable as well as yall are suggesting
