I've thought about it, but I prefer to install things from fdroid so I can get updates without having to check for it on their repository. If no alternatives pop up there soon I may just grab the apk.

I like it a lot, but it has a lot of bugs that drive me crazy. Particularly with the Jerboa app, but also on the web. That's part of the early days for any software, though, especially one undergoing an explosion in its userbase. I'm happy to stick it out, and Lemmy is already a ~90% replacement for what reddit has been to me for the last 10+ years (feels weird to say that).
I would recommend Mint for an easier transition, its what I jumped to from Ubuntu due to Canonical's behavior and I've been happy. It is definitely simpler to use than Debian - which is not to say anything bad about Debian. It's just less hand-holdy. I like it for servers.
Emphasis on "a bit," it truly is a simple task to automate. I don't think that anyone who has need for dynamic DNS should realistically have much trouble tackling that problem.
For anyone who might attempt this and isn't sure how, here's what you need. You need a service controlling your domain with API support for updating your DNS records - some have been mentioned here, I just use gandi.net. You need to enable the API for your account/domain. Figure out how to run the command you need against the API from a scripting language of your choice - there should be documentation for the API, and it should be a single API call. Figure out how to determine your server IP from within the same scripting language. Then, write your simple script that determines the right IP and updates the record if it doesn't match.
All you need to do then is automate running the script - on Linux, a cron job or a systemd service and timer.
There's no game I don't eventually get tired of, but here are three that are fantastic and I can recommend playing for hours and hours:
All indie titles, none of them new, still fantastic and well worth it if you haven't played any on this list. Also all challenging roguelikes, so be warned. =P
