Extracting value on dry flop against fish

Villain is a 28/3

I wasn't sure about my flop play here. Should I be raising a 993 flop and try to get it in? Or just let him barrel his stack off?

In this hand I just decided to stick him in on the turn but I think just calling would've been better in case he wanted to vbet a worst hand or keep bluffing
