Hot take: Only having menus are bad UX because they force the human to search for things instead of making the computer search. I have zero fond memories of trying to find options in the giant menu structures of larger applications. I especially don't understand the reverence of the old-style start menus without a search field many seem to have.
The way I use XFCE is to mark all the applications I use as favorites so they appear on the top level menu, then it’s just two clicks to launch anything, way quicker than click-then-type-to-search.
