Help needed: how do YOU do things?

So, after almost 2 decades I decided to 0lay DND again. Since I have been and always will be forever DM, I've been reading up.

I am very charmed about the idea of foundry (that I have a liscence to (what can I say, I'm impulsive)), but have no experience with.

So: DM's and players that play locally: how do you play?

Do you do oldstyle pen and paper? Printed maps? 3d printed? Foundry for battle and the rest theatre of the mind? Weird combos?

Tell me and inspire me to navigate my fresh crew and myself through this new and perilous world.

Edit: did NOT expect so many reactions so fast here, loving it.
