I asked similar a few weeks ago: https://startrek.website/post/33957879
The answers were all pretty much what you’ve already listed: FreeCAD/OpenSCAD for parametric parts and Blender for sculpted shapes.
The only one not covered in that post was OnShape because I was specifically asking for ones that weren’t SaaS/cloud based.
















Trash? None.
Clutter / work-in-progress: No comment.
