Aside from being based on Fedora 39 now, KDE is now the official desktop environment replacing GNOME. The reasons why are in the article.
The GNOME version of Nobara still exists, but it’s going to be the vanilla version shipped without any extensions (probably because many of them broke after moving to Fedora 39)
Honestly you should just stick to Fedora. If your looking for very user friendly then I would go for Linux mint.
