Thanks for the recommendations.
Solidworks - while the maker level price is attractive, technically I'm beyond the $2,000 / year limit on generated income. Will have to think about it.
Shapr3D - looks promising, will have to dive into it more to see if it would match with how I've grown up designing projects. My methodology follows the draw 2D with exact measurements and then extrude / modify to build up to what I need. Will have to see how well that works in Shapr3D
I'm working my way through Mangojelly's tutorials and they are very good. I'm impressed with the depth available in FreeCAD, but haven't gotten into actually modeling my example project yet. The modeling seems a bit cumbersome / more complicated than Fusion, but that might just be my bias, not having much experience with it yet.
Thanks again.
