Bet/fold every street against a player you describe as passive on this board. Your line would be a reasonable option against a lag however with a low fold to flop cbet and high fold to turn cbet (i.e. villain floats often).

I think your flop calling range is too wide at FR for a player you perceive to be decent. On the flop, villain's calling range is pretty much {55,88-JJ,AT-AQ} and capped at AT-AQ if we don't get raised on the turn, meaning the river is a mandatory value bet.

Re sizing: I'd bet in the region of half pot on such a dry flop (and I'd do this with my entire range) but increase the sizing on turn and river for value as I don't think villain's river calling range in particular is elastic on this board. Our sizing wouldn't then be so large that we'll get ourselves committed by the turn with a medium strength hand.
