For a real hands off approach take a look at Yunohost or CapRover. Both are very easy installs and will give you a gui to manage your applications and other self-hosted services. It's a great way to dip your toes in. The only difference is that with yunohost, they bundle most of the self-hosted services with their own local-sso implementation, so you only need one login for all your services. This is nice if you want a set it and forget it solution. With CapRover, you basically just have a nice gui to manipulate docker installs, so if you find it a bit too restricting, you could just manipulate the docker installs yourself via command line.

Both are great entry points!
