Yeah Fedora with KDE is a good choice, it’s what I run. It seems fairly windows-y (but better imo), and has the things you mentioned at least. Customization is mostly going to be your dotfiles in .config, .var, and you can write scripts to do it (like I have one to redownload everything I need on my personal system if I reinstall, vlc, librewolf, qbittorrent, etc).
Just from the pic, I bet $10 that the second burger is the best one pictured. The first is the one where the patty is full of sawdust and covered in Vaseline for shine, the mayo is Elmer’s and the cheese is plastic, so it looks good for the commercial.
