QJo from SB

[Clinger]

.25/.50 online game, 8 handed.
CO is 30/4/1.3 over ~100 hands. Note says "str84ward postflop"

I have questions on two streets in this hand, so I'll break it up into two parts and post the second part later.

What's our plan for the hand? I usually 3-bet and lead the turn about half the time (assuming it doesn't get capped behind me), and call and donk a safe turn half the time. Should I be more inclined to take one line over the other here?

And as an aside, should I be more likely to 3-bet rather then call flop/donk turn when the pot is large or when it is small? It's not big here, I'm just asking in general.
