@vermaden @justine and for daily drivers most of them don't matter.
SystemD, nmcli, Wayland an PipeWire are those,which you can feel, and two of them are security improvements.

Wayland is fully up to DE/WM developer.

PipeWire you just start as a user service, together with pipewire-pulse and then you use it as PipeWire 0 troubles.

Systemd - when it's daily-driver you just need to remember few common verbs and that's it.

Nmcli - well, that's hard part, so just use nmtui.
