Will we see MFI certified cables for phones?

The short answer is yes. Phones want to maintain their high quality accessories and reputation, and they will no doubt create a process for their USB-C cables that requires MFI certification. While this doesn't make the USB-C cable different from any other cable you'll find at an online retailer, it reassures customers of the phone that their USB-C cable has passed the rigorous testing and manufacturing that consumers already know and associate with the phone product.
