I'm shocked by how much disparate advice you have gotten on what to me look like two very obvious hands.

Hand 1: I would raise the flop every single time. This is both for value (note that you're giving up 1.5 BB by not raising!) and because you may not get a chance to raise the turn. This flop likely hit nobody, so if the turn is another blank, there's a real chance that the SB will check and it will get checked through all the way to you. I've seen this happen far too many times. So the end result will be that not only did you give up 1.5 BB on the flop, but you also failed to compensate for it on the turn. There are, of course, other reasons to raise the flop. The most important of them is that you likely have the best hand, but there are 8 turn scare cards that would prevent you from raising (even though you might still have the best hand even if one of them comes!)

Hand 2: I am more likely to raise the flop here than play it as you did, but I will frequently mix it up. Your line is perfectly fine. And I have no idea why so many people are afraid to bet the river. Your turn raise was not to isolate or to semibluff or anything like that. It was for value! Yes, you'd have likely been in trouble had MP 3-bet the turn, but he didn't. You almost certainly have the best hand on the river, prompting a very easy river value bet.
