I agree that it isn't suitable for hobbyists. For what it is worth, length matching is a function of the layout. Impedance matching doesn't require any crazy manufacturing technique, just choosing the correct pre-preg type/thickness by manufacturer. I've never known a board house who couldn't do it. As for USB 2.0 conversion those pins are directly on the connector [1]. No need for anything beyond routing out those pins to a different connector. USB Type-C is essentially a USB 3.0 connector, but changed to be symmetrical and the SuperSpeed pins are used for other things like DP or other highspeed serial busses.
