Looks fine to me tbh...SQ could be a touch bigger. But given the SPR there is not too much you can do wrong OTT (beside check fold).
I guess given the board we could still be betting a merged range for a smaller sizing. We could also still XC vs his big stab, but I doubt that it makes a huge difference in EV either way here...

Preflop squeeze seems pretty wide vs the 3x UTG open. If you are approaching this spot in a linear fashion, KJs puts you at roughly a 9% squeeze rate in this dynamic. Feels very wide vs UTG/CO. Against CO/BTN, likely better. If you are looking at it form a polar perspective, KJs is nowhere near making it in there in this line.

I would personally set my squeeze range up vs UTG/CO something like JJ+, AQs+, AKo and A5s/65s/54s. Lets face it, if we are squeezing KJs or 65s, both hand classes are looking for folds preflop. I would rather have hands in there that are easier to play postflop or vs. 4 bets and that also don't face the domination issues that KJs faces.
