I know in zsh, fish, and nushell, you can press a key combo to jump into a text editor of your choice. You write your command there, with all the power and shortcuts in emacs, vim, nano (whatever you like to use). Then you save and exit, and it appears in your command line, ready to execute.

Personally, I don’t think anyone new to Linux at this point, who isn’t tech-minded, should be pointed to an X11 environment. So until Mint devs have ported Muffin into a Wayland compositor, I wouldn’t recommend it. They’re used to a shiny experience visually, so I’d go with Plasma 6 running on Fedora or OpenSUSE Tumbleweed.

I use a Beelink SER5, but that’s because I also plan to set it up to be a retro game console, in addition to streaming.
