If you need dashed or dotted or styled lines, at the moment that's the only workaround we can offer.
The built-in lines are using QTriangulatingStroker under the hood, that seems to be missing that part
of the QPen features (brush, style).

as for map polygon, the only workaround i can think of, if mapboxgl does not offer it/is not an option, is
to use a MapQuickItem instead, create the polygon with Shapes, and then do the math and georeference it "manually".

As for your last question, i don't think i can answer since too many details are missing

hope this helps a bit, anyway
