I think Cardigan is right here. If the cable isn't being used as a transmission line (more strictly if the transmission line effects are negligible) then capacitance is the dominant factor. It can be treated as a lumped capacitance and the effects of inductance will normally be negligible in such applications. This would cover audio for most distances and RF for short distances where the wavelength is much greater than the length of the cable.
If the cable is being used as a transmission line, either because you want to or because the wavelength is significant, then both L and C matter as Mike Watterson correctly states. In practice I think you would normally measure the characteristic impedance of the cable. Actual L and C are irrelavent, only their ratio matters.
