The best two are self teaching and one to one teaching.
Both are, of course, "boring classical setups" but both can be improved by technology. My daughter had one to one teaching over video in subjects that we would have struggled to find a tutor for locally (classical civilisation, for example). Self teaching is hugely improved by access to more materials - this does not need fancy tech, but just websites and videos can help a lot.
