Stroke weight should not factor into scale of object.
This should work more like Illustrator, where PATHS determine size and snapping

What are the other options? I deselected "Dimensions Include Stroke Weight" & it still has the bounding box on the outside of the stroke
Unless I'm misunderstanding your request, that is user selectable. Hamburger Menu (top right of application window) and deselect "Dimensions Include Stroke Weight". There are a few other options that impact how strokes behave when scaling, too.
