I'm using rootless podman without any issues. I only had to create subuid and subgid mappings. I didn't need to modify any kernel parameters to get cgroupsv2 to work. According to [cgroups(7)], modern systemd should automatically mount cgroups2 hierarchy under /sys/fs/cgroup/unified - so I think this is the path you need to look for to determine cgroupsv2 support.
