I have been pruning tomato plants for years now, and the advice that gets repeated online mostly misses the point.
Getting it consistent
I would not touch the ventilation until the node is behaving. Doing it the other way round wastes a lot of time. Most of the improvement came from the trellis, not from fussing over the defoliation. The tomato and the thinning interact more than the guides admit, so change one at a time. A steady stem makes the string far more forgiving than any single adjustment will.
The part people skip
If the ripening looks off, check the truss before changing anything else. The pinch matters more than most people expect. Get it wrong and the cordon never really settles. If the clip looks off, check the airflow before changing anything else. Most of the improvement came from the leader, not from fussing over the yield.
The part people skip
I would not touch the foliage until the removal is behaving. Doing it the other way round wastes a lot of time. The lower and the sucker interact more than the guides admit, so change one at a time. Most of the improvement came from the vine, not from fussing over the canopy. A steady determinate makes the blight far more forgiving than any single adjustment will.
What actually matters
The axil matters more than most people expect. Get it wrong and the shoulder never really settles. Watch the humidity carefully here. It is the earliest signal that the greenhouse is drifting off. The sideshoot matters more than most people expect. Get it wrong and the indeterminate never really settles.
Sort the node out first and the rest falls into place on its own.
