BTN vs BB

Please don't post results. If you do, you can't know which advises are bias and which aren't.
Preflop, Flop and Turn are fine.
OTR you have to weigh two options against each other. Just calling and maybe missing out on him calling a raise with a PP or 4x vs raising and potentially opening yourself up to a 3bet and maybe feeding 8x and very rarely QQ+.
What do you think is more likely?

Bet Flop ~33% you can get calls from weaker Ax, Kx, Qx but it´s also ok when he folds some Ax, Kx, Qx combos because all these hands have at least 6 outs against your hand. (Except the A2-AT,KJ, QJ these hands have just 3 outs.) Lets call it a value/protection bet.

The problem is if you bet to big then you will isolate yourself against a stronger range. So that all weaker hands fold and all better hands call.

If you think that villain will also shove on river with a weaker pair or Ax, Kx then just try to get it in. Otherwise just call the river bet.

He bets the pot so I like just to call here. You splitting a lot with other Jxx so by raising you create more rake for Pokerstars. Both of you losing money, Pokerstars wins. And in other cases he has 8x or folds his bad hands.

Donkey line on river from viliain,min 3bet. Play simple, just call OTR. Everybody play fancy this day...

I think that this re-raise of the villain shows a lot of strength. Mostly in NL2.
I do not see him doing it with medium pair, so I'd fold.
