The key difference to me in science fantasy vs pure fantasy is generally around whether mass production can be applied to its distinguishing superpowers. The force in star wars can't be manufactured or welded in a manufactured manner. Magic in dungeons and dragons must be wielded by wizard specialists because it's application can't be industrialized for (insert setting reason). Because industry is about taking novel techniques and bringing them to the masses. The force and magic is about exclusivity in wielding the power, not being generally available to the public.
