…I still use QCAD for quick 2D sketches for the workshop. …
Me too! QCAD is excellent for all things 2D like templates, checking dimensions & geometry, layouts, profiles, and floor plans etc. I also use it lots to redraw bits of published plans to make sure I've understand them. Not all published plans are, ahem, completely accurate. Probably the greater number of of my CAD drawings are done in QCAD. Whilst mostly simple 2D drawings are still very useful and often 'good enough'.
But when the planned thingy gets more complicated, I find it helpful to switch to a 3D package because it's much easier to visualise objects in 3D, and because you can experiment with dimensions without breaking the design. FreeCAD is good for creating single parts, like a crankshaft.
Fusion360 is better than FreeCAD for creating single parts in that it has even more ways of constructing them, but it really shines when you want to model an object, like an engine, that has many fixed and moving parts.
