And although I'm experienced in modeling in 3D, again, I'm seeing a very steep learning curve in going from AutoCAD to FreeCAD.
Having used AutoCAD in the past, that's definitely true. The whole parametric thing adds a level of complexity, as well as the constraint-based sketching. Not to mention that FreeCAD does not have a single, unified and polished UI. I've come to see it rather as a collection of different CAD approaches merged together. When you understand the distinctions between the approaches and learn how to take advantage of them, you can do a lot of things, but that'll require some time.
Speaking of approaches, one way to sketch your profile is to use the
Sketcher Polyline tool and sketch straight segments, then use
Sketcher Fillet on the corners. Then you'd make the outer and inner arcs concentric by setting coincident constraints to their centres.
