Natural is totally unnatural.

Rclone is awesome. Mega and PCloud got native clients that works great. Nextcloud is an alternative.

Fedora uses grubby to edit grub. Read documentation. Do some research.

Wofi ok. Rofi-Wayland great. Tofi awesome and enough for my use case.

When it got software/features I don’t use.

I don’t do derivatives. Arch based distro? Just use Arch! Ubuntu, Mint, Pop or the hundreds alike, go Debian!

LC_TIME

As both arch and gentoo has very good documentation, and is very standard Linux as it “always” has been, I don’t see anything hard about them. Nix is a different beast and you need to learn some new approaches.

Have you tried sfwbar as a tint2 replacement? It's rather cool and very customizable.
