Freecad and openscad are basically your only choices for FOSS CAD work Freecad has pretty bad UX compared to Onshape and Fusion 360 (have to keep switching between lots of modes rather than a single unified UI), while openscad is more of a CAD DSL (that IIRC doesn't actually model solids as solids).

I use CadQuery(1). It uses OpenCascade and BREP under the hood. So far, its been pretty decent to work with.

edit: I also use Fusion360 for non-scripted stuff. The parametric modeling is nice!
