| which is more important? which of these three is more fundamentally more important? I think it's the quanta of spacetime. Permittivity and permeability are classical macroscopic concepts which do not have any quantum analogies. The couplings only relate to the forces. If there is only one force then all the coupling constants are not necessary for a theory.
