I tend to pot up in stages, but never for a specific reason, other than it seems to be a more practical thing to start the small under the indoor plant lights, but they manage better in terms of enough water if they are in larger pots once they are outside.
I have some seedling Vincas that got (accidentally) started in a large deep tray of soil, so a big pot indeed. Many of those are ready to be transplanted into the ground now, once I can find the time.
