I use Docker on my Pi for one simple reason: management. While it's true that some services are set and forget, there will be times when you will need to check on a particular service's health, and Docker makes it a little easier by having each service on it's own environment. You can restart every service individually with ease, and even nuke something if needed without wrecking the whole system.
I use Portainer, and everything on Docker inside it.
It is up to you. Using Docker makes it easier for administration and evolution, but bare metal is sufficient if you are comfortable with it (which every self-hoster should be).
If you're already familiar with it and can maybe even reuse some compose files, it's definitely worth it. Even on a Pi.
I just installed paperless-ngx on my Pi with Docker. I read the instructions on doing it bare metal and thought "Nope!" So yeah, it can save you some work.
Yes. Using docker is not like running your services inside VMs. It's a pretty lightweight way of structuring your services, with the host kernel shared by all instances.
I run everything in Docker on my RPi 4 and it works very well.
