If you want the best tutorials on FreeCAD, check out mangojelly on youtube. He has a current 1.0 beginner series that starts right from the very beginning. And he goes slow enough to easily follow along.

Ignore the huge number of workbenches. You can even go to the Settings and turn the ones you don't need off so you never see them again. You are only going to use 2 workbenches 90% of the time-- Part Design and Sketcher. And as you get more experience, you might add another couple of workbenches as you go. Most of the third party workbenches are specialty things. For example, I sometimes need to design and make gears or do small sheetmetal work. So I have the Gear and sheetmetal workbenchs installed. You probably would never need it.

Learning CAD, no matter what flavor, does require effort. It's as much about learning how to think as it is about learning how to do.
