Thunderbolt
First of all, no device manufacturer is going to take up space for 2 connectors on a small electronic device if that's what you're suggesting.
Also, other protocols can run on the USB-C type port. Thunderbolt 3 & 4 use a USB-C connector. Apple has been using it on their laptops for years. I suspect if they need the speed of Thunderbolt for data transfers, it will be on the premium iPhone at first. But honestly, I don't know many people that plug in their iPhone to transfer or transmit data ever. So I think Apple will probably use a standard USB-C port.
