If the idea of adding more to your duties as a recreational sysadmin doesn't excite you, a Synology is fantastic. And there's quite an extensive array of app packages you can run on them with nice interfaces.

However if you're looking at doing more than basic storage, you might want to look at something like FreeNAS, Proxmox or Unraid. I've no experience with any of these but if you're wanting to do a lot of app containers for stuff like databases, media servers, home automation, Unifi Controller, download managers etc, these might make more sense.

I personally run a dozen docker containers on my Intel CPU Synology, but I wouldn't describe it as a seamless experience. I do 99% of the docker administration from the terminal (via ssh to the nas) and maintain it with custom shell scripts. I'm very happy with the outcome as I get the benefits of Synology (Hyper Backup being a particular highlight) and docker containers running on hardware that was running 24/7 anyway.
