>>105981523 (OP)don't ask generic questions because you will get answers from people who know less than you, and are probably retarded.
since you have some time before the switch, start using MSYS2 and familiarize yourself with the terminal, shell (bash, zsh), coreutils (ls,cp,...), package manager (pacman), and the workflow of installing packages via the said package manager. that alone will give more applicable knowledge than 99% of "linux noobs", before you even install a linux-based OS. and you will be aware of how using the CLI is not a "limitation", but rather an advantage. the biggest advantage of all in fact.
if you get this far, you can start looking at PKGBUILDs to see how packages get built, although that's not strictly necessary for you as a beginner.
when the time comes for the switch, install Arch, which will be relatively easy since you already familiarized yourself with pacman.
don't install KDE, or any DE. all you'll get from them is unnecessary bloat and bugs. all you need is a window manager, and a panel (if the WM doesn't come with one). Openbox is a good choice. it's also an X11 choice instead of Wayland, which you should avoid, at least for another 3 years.
