OpenSCAD as well. I bounce back and forth between the two of them a fair bit depending on what I'm doing and which one's going to be more ergonomic for the problem at hand. The Fusion 360 built-in chat thing... not so good in my very limited experience.

Second this. Since Opus 4.6 there's been a very noticeable bump in accuracy at just doing FreeCAD+Python or OpenSCAD code, usually one-shots things with basically described geometry.

Recently, Sonnet 5.5 got quite good, too, but not at the level of Opus/Fable for complex geometry

Disclaimer: I use it for very precise 3D printing, not woodwork.

I can imagine. I did a bit of poking with blender and the api use got better there as well. For my use case I needed BREPs so stuck with freecad. I'm tempted one of these days where I have a pile of extra tokens to see about converting it to directly use the Open Cascade library since I just need to model and not the UI.

Seconding openscad (havent tried freecad to be fair) with opus 5.5

I had it design a model sailboat hull, and it fucking nailed it. It even designed it for printability. I’m genuinely really impressed.
