Im using linux for ±3 yrs and im pretty used to it. Im currently running nixos on my laptop. My question is what kind of hardening do i need firejail, apparmor, selinux, … all 3 of them ? none of them ? Thanks for the advice and have a nice day

    I dont think so. Both UFW and firewalld are just frontends - they don’t actually do any work themselves. That is all handled by the iptables or the newer nftables kernel modules inside the kernel itself, the major difference will be in what rules they create but both should be able to create the same rules for either of these kernel APIs. UFW is what ubuntu uses by default I believe and firewalld what a lot of other distros use by default.
