I've used Nextcloud for my Contacts and Calendar for several years now. Works great on my iphone and linux computers (evolution + gnome-contacts/gnome-calendar).

I also use Nextcloud for my Notes/Task Lists (also works great with iphone and evolution), bookmarks, and recipe management.

My only issue with Nextcloud, is I really with they had an LTS release with at least 2 years of support. I have to keep my server moving between major versions pretty much every 4-6 months (you can't skip versions), or the clients which tend to get auto updated (especially on iOS) stop supporting the older server versions.
