Great you find what you were looking for.

I guess these are inherited from the old 1.x and 2.x Ftools/Gdal menus

>(like "Select by location"), and when not (Extract by location).

From memories, old tools of the Ftools were kept in the menus for coherence with previous versions. And new algs were added based on the assumption of their use by the vast majority.

Personally, I no longer use the vector/raster menus; all these functions are shortcuts to the Processing tools so better directly look at the Processing toolbox where more functions and a search box are available
