For me, most of the things I self-host work better running on my local network, namely home automation and home theater type stuff.

Also, I don't expose any of it directly to the internet.

IMHO Docker has been a godsend for deploying self-hosted software.

I haven't tried it yet, but watchtower (https://github.com/v2tec/watchtower) can be used to automatically update running Docker containers.
