My vote: not if you can avoid it.
For casual home admins docker containers are mysterious black boxes that are difficult to configure and even worse to inspect and debug.
I prefer lightweight VMs hosting one or more services on an OS I understand and control (in my case Debian stable), and only use docker images as a way to quickly try out something new before commiting time to deploying it properly.
I found they were easier to config. somebody has a yaml file or via portainer to setup ports etc. and you can always bash into a docker to lurk inside the black box
I think they’re easier to debug as well IMO. Logs can be spread out across the filesystem on something like a Debian VM. Whereas with Docker they’re all in one feed you can easily follow the output from, with different services colour-coded. You can also easily increase the verbosity by editing the compose file.
