Hmmmm... even though I'm a cheerleader for it, I wouldn't recommend starting with FreeCAD. Learn on something more feature-complete and with a less idiosyncratic UI, like Onshape. I learned Solidworks at work and without that foundation I wouldn't understand what's wrong / missing about FreeCAD (which is still a lot).
When I finally Get Around To™ learning CAD, I'll definitely invest my time in FreeCAD.
