Low end of a OESD on the flop - is it correct to bet here?

Basically is the bet on the flop the right play here given the small pot? Is this a situation where you want to semi bluff with the idea of:
a) winning the pot straight away, or
b) making any marginal hands fold, or
b) getting a free card on the turn.

Would it be better to check raise?
Or would it be better to check and wait for the turn?
If the hand had been raised before the flop and the pot was larger would it be correct to now make the semi bluff bet be a better play?
