Hey
@Enjoying ,
I'll give you my thoughts from a quadlining perspective although I know that's not specifically what you are trying to accomplish.
I top above the fourth node and remove nodes one and two completely and let the two branches each from nodes 3 and 4 grow towards the outer edges of the pot, keeping them relatively horizontal as they grow. The I use some of the small branches that form off of these main branches to fill in some of the gaps.
The reason for keeping everything level and flat is to help spread the growth hormones evenly across the plant. If any of the individual branches are allowed to grow higher than the others, like some of the ones on your plant, those branches will get a disproportionate amount of those hormones. And the same applies to flower.
You look to be growing outdoors and, if so, will soon be subject to lengthening nights (assuming northern hemisphere) which will trigger flowering. Any cutting of tops or branches will have the plant spend time and energy in repair mode so that should be factored in to your plans.
Another training idea is LST, or Low Stress Training, which involves bending the taller branches and holding them down with string, pipe cleaners, weights, etc. to help spread those hormones.
So, given your proximity to natural flowering, any topping or thinning should probably be done soon. Any lower branches that won't make it up to the main canopy can be removed to redirect any energy, hormones and nutrients to the other branches.
And that's what I would probably do with your plants. Tie all of the branches to a relatively equal height, with the tallest ones bent horizontal and the nodes spread out as best as you can.
