I didn't know NextCloud was P2P (I thought it was just based on a central server with a bunch of clients) - what's the P2P part?

You can share content with users of other instances, or import content that is being shared with you into your own account. This is federation, but still quite limited.

Example: I can share a folder from [e-mail] with [e-mail]

Syncthing is equivalent to the file-sync portion of Nextcloud and really is p2p FWIW. Been happy enough to replace my Onedrive subscription and once set up, just works.

It's not peer-to-peer, but you can share files between Nextcloud instances.
