I really like the ease of the digital world, but I perfectly understand the points presented by @slyflourish about the use of paper character sheets. It’s strange to say, but using paper character sheets and printed books is quite liberating these days. @ferslvra
I have them create characters on paper, and play from them, even when we use Foundry or Roll20. But once they're created, I fill out PDFs so that I have the official current versions. This way the game remains a paper tabletop game, playable with physical rules (any TTRPG that isn't is too much for us). The computer is just my flag planted on Mount Lazy.
My advice to VTT developers: I'm not interested in trying to turn my tabletop campaign into a video game. And I don't want to spend more time ditzing about with complicated interfaces than I do with writing a good adventure for my players. Just give me clean, SIMPLE tools that enhance storytelling and keep things flowing.
