I think another good argument for phones is that it's surely much easier to clean lint out of a lightning port than a USB C port.
Edit: But probably, I'd guess, right now the main reason Apple has stuck to lightning to whatever extent it is is because it's more convenient for its customers. USB C is already the standard, and Apple would benefit from switching to USB C across its product line if its customers would like that more.
