Three streets of valuebetting seems (slightly) too optimistic in this specific spot. Both you and villain have too many stronger hands to do this in my view.

I would alternate between the following two options, preferring the latter in general.
(1) checking AJ on the turn, to calldown is effective.
(2) betting turn to check/call river is effective (if opponent is capable to turn hands into a bluf - otherwise x/f is decent too)

WP
He has a ton of worse hands to call with, like Ax, worse 2pairs and like the occasional hero calls w/ like Kx.

Sizing ott might be a little small but not that much.

This is one of those hands we're we just have to go bet-bet-bet since we get called from a lot worse and also if we say check the river villain will sometimes check back worse that he would've called off with and also shove better and we hate life but sigh call hoping he value shoves worse or turns a like KQ/QJ into a bluff which is hoping for much at these stakes. =)
