I like your play through the flop.  Your raise pre is just fine (assuming 2150 is your standard raise at this level with your full range).  I'm good with your flop cbet as well, but maybe not the sizing.  Is this your normal cbet sizing?  Less than 1/2 pot either means you're weak and trying to steal, or you hit a ten, not afraid of the board, and you're going for value.  If your normal cbet IP is 1/2 pot or so, then you need to stick with that.  You have position and you could very well expect to take this down most of the time.  Auto-piloting and not being prepared for a check raise isn't a good sign, but at least you notice it now.  I always try to think about what I'll do vs a raise or check raise before I make a bet on every street.  

You also question, “… paired board makes we wonder what hands are we ever getting value from here?”  I don't think I'd consider this a “getting value” spot.  You don't have a made hand, so what you're doing is semi-bluffing, not betting for value.  I think the kinds of hands that can c/c here (and don't reraise pre) are: 55-99 (possibly TT and JJ), AXss and KXss, TX — and some of these are in his c/r range as well.  He could be capable of an OOP float as well, so I'd add air to his range like AspadesX or KspadesX, or a gs with a spade blocker.

He can be c/r here as a bluff, semi-bluff or as a value raise.  At this point you can fold, call or rr.  You have too much equity so folding is out of the question.  He's only got 30bb's behind after this raise, so if you 3b you've got to consider a possible shove either for value or a bluff which you can't call.  If you just call, you're getting 3:20 pot odds on your money (3bb to call, pot =7.3bb pre + 12bb on flop).  This is about 15% to call, and your chance of hitting the flush is roughly 36%. I'd make the call here and assess the turn.  

You can check behind or just call on the turn if you miss (depending on his turn bet size and pot odds offered).

You don't mention any reads on this opponent, so I'd just stick with the hand as long as the calling odds offered are good enough to continue with your draw.
