Lightning is not a better connector. It maxed out at USB 2 speeds and I needed separate bespoke adapters and chargers. I can now use standard USB C cords with everything, standard USB C headphones, connect my iPhone to my portable external monitor with the same USB C cable I use for my computer…
And the iPhone supports all of the USB C standards that computers support - audio, video, mass storage, network, keyboard, mice etc
Side note: USB 3 Lightning did exist on iPad Pros.
