Yeah defo bet the flop, not just because some pairs don't call bets on certain turns, but more importantly because any Jx he has is likely calling 3. Don't aim for 2 streets when there are combos of hands that call 3, especially when he could well be stationy with weaker parts of his range given hes basically unknown to us. Flop and turn are the best streets to bet here even if you were only going for 2 streets, since there's a club draw and like you say overcrads can induce folds from 77-TT etc. Rest of the hand is standard/well played.
