I'm in the same boat! I got tired of the constant enshittification of Fusion360 and started learning FreeCAD. And wow! it's way less intuitive.
But I think I'll push through, as I don't want anything but open-source for this. The reason being that I don't want the same thing to happen again: I spend an unholy amount of time learning how to use a CAD software, and then it becomes the hottest steaming pile of corporate shit possible and I don't want to use it anymore. That's why I haven't even started looking at OnShape.
With open-source the biggest risk is that the same thing might happen if the project gets abandoned, but it doesn't seem to be the case for FreeCAD (at least in the foreseeable future).
In any case, I'm interested in hearing what others have to say :)
