Podman is great, but a lot of confusion arise from the rapid development the last ~year and the fact that different distros have relatively old versions in their repos.
I recommend using the latest Fedora Server and defining your containers as quadlets. Also, on Fedora, yoi can install Cockpit (and cockpit-podman) and get a decent webgui to manage your host and container.
I should just write a blog post about this instead of typing this up on my phone in bed 😆
Fedora has been “just working” for me for the last couple of years. It is my go to for older relatives for that very reason.
