Mortals & Portals is very good. They made the decision to use PF2e like 2 weeks before they started recording, and learned the game on the fly. Sometimes they trip over the rules, but they also illustrate how to fail forward in that regard.

They also run it as a Theatre of the Mind game, which a lot of people will try to convince you isn't really feasible. They fease it just fine, so I like it as an example.

Narrative Declaration also has several campaigns on YouTube. Rotgrind and Rotgoons are campaigns set in a gritty homebrew world. They had an aborted Abomination Vaults campaign that started off with the game's beginner box. They're currently running Rusthenge, which is a different beginner's adventure. They also have a series of "teaching Pathfinder 2e to VTubers" campaigns, which... They're good, but they're just the beginner's box over and over again, with different cartoon variety streamers. They use Foundry, and play gridded combat.
