I found zeroing in on a specific package and learning the specifics of the parametric modeling AND a particular end goal to be useful. Doubly so if the YouTuber is making lots of videos on other topics that might be helpful. I learned on an olllld Fusion360 tutorial series from NYC CNC, but my more recent FreeCAD learning has been from MangoJelly: https://www.youtube.com/@MangoJellySolutions
