I don't know to what extent you got molested by the prophets of immutable distros yet, but I can only recommend to join the cult. Install Fedora IoT (or CoreOS) and simply know that you'll get a working container host (powered by podman) with every update. The whole discussion about which distro might survive whatever massacre the respective package manager commits next becomes superflous: You simply get the next image that was built upstream solely to serve containers. The whole package-udpating-shengiangs is done by other people for you, you only collect the sweet result. The only "downside" is that one has to become familiar with containers, but since you run docker already that should work out. Also for stuff like tinkering with the latest tools, just put those in a distrobox. That way they are indipendent from your solid container host, and you can mess them up in whatevery way you fancy and dispose them without any traces left behind.

Edit: To give one more example why this is awesome: It wouldn't even matter which one you install, you can just rebase to the other (IoT lives in the fedora-iot remote. silverblue, coreos and the others in the fedora remote. Just for anybody who might be confused by only looking at ostree remote refs fedora)
