I've run Nextcloud for years primarily for webdav file sync and calendar+contacts. It pretty much just works. That's not to say there isn't any jank, but it's mostly if you try the more obscure apps e.g. I've set up the phone track feature and it worked for a while, but I've had trouble with it recently. Probably fixable, but I just haven't spent the time.

I would say it is the core component of my self-(vps)-hosted setup and easily the most valuable.
