I think it's suuuuper close between betting out and check-raising. I'm pretty unsure, so I was hoping to get other view points as well. Personally, I probably check-raise because people in my games two barrel too often, but I'm not confident in that at this level.
I'm thinking c/r is my play because it fits with why I only called the flop, but I agree it's pretty close. If I chose to bet out though, I think I'd 3-bet the Villain if he raised me, but just call if anyone else at the table pulled a c/r of their own. Then reevaluate the river.
I'd lead the turn bc we're unlikely to get two barreled lightly in a live low limit game, imoIs it a bet/call or bet/3bet? Obv villain dependent but vs a typical loose/passive bet/call > bet/3bet?
