Docker, there are more resources for it and once you know it Podman should be an easy migration if you want to. Also I'm not sure about your claim that Podman is more FOSS than docker, it's "better" because it doesn't run as root, but other than that I don't know of any advantages to it that are not a derivation of "it runs as a regular user".
On the same machine I have Docker running as root and not as root. I choose which version, root-ful/root-less depending on what the container needs to do.
I think the only advantage is that Podman runs as root-less out of the box, where with Docker you have to do a few extra steps once it's installed.
