QJs 180-man IP

I have no idea about his min 3bet range but lets see...

I would check back flop. Hes checking kings and Qx, maybe some lower pairs against which you dont have multiple streets of value anyway. Hes probably slowplaying top set sometimes. And flushdraws should be betting. IDK if he bets them, though. Seems like a fishy player with a ton of nonstandart/bad lines. You want to keep the pot small until the turn where you can get more info.

As played call the river. A good player would probably not bluff as much because he cant rep Ax or a flush. But a fish might make a bad bluff there.
That should cover all strong hands, now onto the weaker ones.

He bets on the smaller side, maybe he thinks its a block bet with a KK and Qx. But if he does this with KK, KQ, QJ and QT, you still have the correct odds to call.

If I was him I would Cbet flush draws as well. That’s why I think the river is almost a blank and with 2 aces on the board you can bluff catch. Also, betting the flop is close with middle pair. If you want to keep his range wider I would check and her-evaluate turn, because there aren’t many better hands that would fold and I don’t think you will get value as well.

Was not too bad considering the limited info
