I’ve used Fastmail with a custom domain for a few years now… (5+?) and have been really happy with it. I wish it was a bit cheaper (or had a better family plan), but it works well with my terminal email client (mutt).
The web client is pretty quick and I use the calendar there all the time. Fastmail supports all the normal standards such as CalDAV, so you can use it with third party applications.
You can self-host libreddit, which is what I do, and it will still continue to work. That said, it is on borrowed time as development has mostly stopped.
All the public instances are unusable b/c of the rate-limits, unfortunately.
