But why is USB C directional? One phone I have won't charge if the cord is in one orientation but fast charges in the other orientation.

It isn't. Either your cable is bad, or the port on your phone is bad/broken.

Symmetric is the default but not required by the standard, so directionality is permitted if irregular.

Technically cables are part double sided (USB3 wires, grounding) and part single sided (power, USB2), while ports should be double sided.
