The thing to know about Nextcloud is that it can be thought of as an
application container.  If you don't want file sharing functionality,
disable those bits, etc.  You don't have to have all that Nextcloud
offers just to have CardDav/CalDav support.  Additionally, using
Nextcloud for Card/CalDav could give users an alternate webgui to manage
their Card/CalDav data.  That said, I do agree that Nextcloud for just
Card/CalDav alone would be overkill (but it will certainly scale and
it's robustly supported)
