Seems like they've made cockpit easier to use on openSUSE.
https://news.opensuse.org/2026/03/18/new-launcher-aims-to-simplify-cockpit-installations/
On Fedora installing and autostarting is as simple as:
sudo dnf install cockpit
sudo systemctl enable --now cockpit.socket
And to allow it through the firewall, if active:
sudo firewall-cmd --add-service=cockpit --permanent
Then it will be available on https://localhost:9090/ (with a certificate warning)
