This "root categories" found on 2020 March 5th using Special:UncategorizedCategories (has lot of empty ones, I added discussion for the one who should not be root -> to find my comments with specialpages )
Category:French or [[:Category:Francais]] ? -> no answer, I created Category:French
Not accepted: I would perhaps create a category type, with, under:

<categorytree style="margin-left: 30px;" mode="categories" depth="0" showcount"on" hideprefix="never">Images</categorytree>
<categorytree style="margin-left: 30px;" mode="categories" depth="2" showcount"on" hideprefix="never">Help</categorytree>
all contents in texts = <categorytree style="margin-left: 30px;" mode="all" depth="20" showcount"on" hideprefix="never">Texts</categorytree>
<categorytree style="margin-left: 30px;" mode="categories" depth="1" showcount"on" hideprefix="never">Texts</categorytree>
Note: for me, "Tools for Translation" should be on EN wiki, maybe under Help
all content in Music = <categorytree style="margin-left: 30px;" mode="all" depth="0" showcount"on" hideprefix="never">Music</categorytree>
<categorytree style="margin-left: 30px;" mode="categories" depth="1" showcount"on" hideprefix="never">Maintenance</categorytree>
