Well, if you are new to Linux, it is better if you just install new distros to try them, I would go to Arch Linux as it’s the cleanest distro, I could install multiple DE without issues, but then it’s a bit mess of packages, also it’s harder to install, you need to type archinstall and understand their options. I have a desktop and laptop and I always use the laptop for testing, if you copy the ~/.config folder, you can restore all your applications settings (just copy the app settings you are using), ~/.mozilla to restore your browser as you had it before the wipe and some more settings are under ~/.local. I also copy my ~/.zshrc because I have a custom prompt, configs, add-ons, alias…
