Right -- my trig is weak. Joan Horvath's "Make: Trigonometry", which teaches with OpenSCAD, is on my reading list [0]

bRep environments liberate you from trig to some extent because you can build on arbitrary faces and edges, so you'd get some of those parametric, auto-updating benefits with Build123D or CadQuery.

FreeCAD's sketcher tool means I've only resorted to trig a few times.

Yes -- me too!

Such a neat idea.
