I use and recommend specifically labelled seedling mix and/ or compressed peat pellets to start seeds.
I then transplant 16oz nursery pots with promix HP.
I choose products without “ moisture control” or fertilizer added as I prefer to control both water and fertilizer myself.
I don’t think I would choose to try a cactus mix, presumably with a lot of sand for tomato or other veggie starts
