Dawn, I grow a lot of vegetable starts indoors.
I use 2” starter pots:

and 10”x20” plant trays:

You can get 45 of the pots in each tray with a little room to spare, then move some to another tray to make more room for plant foliage as they grow. I prefer them over the multi-pot inserts since you can remove each pot and transplant when it's ready. The pots and trays are reusable.
