Yes I would CB that flop. You want to get value from weaker Aces and single hearts.
As played river is a tough spot. You're getting pretty good odds on the call so the question is whether he has enough worse Aces and missed flush bluffs in his range there. That has to be balanced against the better Aces, flushes, and boats in his range.
