I'd play it the same way. You say he's lag pf so this could actually be a worse queen waiting for the turn. It could also be a hand like AJ/KJ/TJ/J9 etc. raising for a free showdown. Finally, even though you say he's a little passive, it could be a semibluff raise with TK, AT, etc.

A lot of guys will bluff their missed draws on the river so I like check/calling there. The only reason to bet the river is if you think he's taking a free showdown a lot with a worse hand, but I don't think he will be and I wouldn't feel comfortable folding to a raise.

I also don't like 3betting the turn because missed draws bluff so often and 3 bets is too many imo for your hand as you are behind a decent amount of hands.
