I highly recommend lst, it keeps your whole canopy at the same distance from the light so you don't get any monster colas but you get lots of decent sized stuff and you get to control the height of the plant. My other half would only let me experiment on one plant in our first crop, the ww in my journal, so I just have one flat plant! And the others were all taller than it so it didn't really get a fair trial but it still did pretty damn well, and the whole plant is probably less than a foot tall, compared to the others that are at least 3 or 4 foot. I didn't do that one until fairly late in veg but my cheese plants were topped, fimmed and trained to control size from very early on because I needed them to stay in the veg closet a few months, they're proper sturdy looking little things, exploding now at 4 weeks in flower.
I'm going to keep using coco, it's great except for the damn gnats! Use bricks, they're less likely to be full of gnats, and don't overwater! My cheese plants are in coco only and it takes forever to try, my white widows had perlite in but I should've used more, they were my first grow, the coco seemed to shrink towards the end, like once the roots had filled up the coco it seemed to compact slightly. My heisenberg specials have a much higher percentage of perlite than the others did, about 40-45%, and are in smart pots, they dry so much faster and I prefer it that way although I'd still like another 10-20% perlite but I'm at home a lot to keep an eye on them drying out and hand water, if I had less time to spend on them then more coco would work great.
That's the only stuff you mentioned I have experience with, good luck with your grow man, hope you learn a lot and it goes well for you
