FreeCAD is a spectacular second CAD tool to learn. Once you understand the concepts and workflows for one of the industry standard tools, you will know how to translate that to FreeCAD speak as it were.

As a first CAD tool it is atrocious. It crashes while you are exploring new tools and you just don't have the vocabulary (or muscle memory) to actually ask questions or search for answers.

If someone really wants to get into hobbyist CAD (for 3d printing), probably the best flow is to start with TinkerCAD, switch to Fusion 360 (assuming you aren't running linux. Onshape if you are), and once you are comfortable and can build basically whatever you want change to FreeCAD if you want more control over your toolchain.

And if someone wants to do this professionally? Fusion 360 is the endstate. Maybe you'll end up at a firm that uses the other family (which I think Onshape is part of?) but you will basically never find a company that wants FreeCAD formats.
