I would not recommend using ufw today. The configuration easily becomes unmanageable and inconsistent over time, even if you try to be consistent when configuring it. I think ufw also still relies on iptables (using a legacy shim since the underlying distros have all migrated to nftables by now). firewalld is a more sane default for a high-level firewall for systemd-based Linux distros these days.
