Are your Docker containers connecting to the network (eg using ipvlan or macvlan)? The default bridge network driver doesn’t expose the container publicly unless you explicitly expose a port. If you don’t expose a port, the Docker container is only accessible from the host, not from any other system on the network.
Yeah of course, that’s what I’m doing anyways, but the purpose of a firewall would be defense in depth, even is something were to be published, the firewall got it.

They are Only in my docker bridge networks and have a few published ports
If you don’t want the Docker container to be accessible from other systems then just don’t publish the port.
