Lightning does not mandate USB 2.0 speed - there have been lightning ports on iPad Pro models which were capable of 3.0.

Likewise, USB-C ports on a spec-compliant device do not indicate greater than USB 2.0 speeds (e.g. high speed), nor do cables with USB-C ports on both ends indicate greater than high speed.

In fact, there are plenty of devices with USB-C ports which do not support data channels at all (but these tend to have compatibility issues due to not being able to negotiate power delivery)
