Is this the correct amount of action?

UTG is 31/14 and aggressive postflop.
Button is 40/8 (100+ hands) and tricky postflop.

My thoughts: Based on button's PFR%, I felt he had big overcards or 88+. That is why I 3-bet the turn. After his cap, I still wasn't convinced that I was behind, so I bet the river. I pretty much ignored UTG throughout the hand as he just kept calling.
