My phone is waterproof yet has USB-C connection for charging. I used it several times for underwater photography, awaited water to dry then charged it without any issues. Only saltwater was a problem and had to replace charger after charging became non reliable (I needed to plug the charger several times before it worked and subsequently changed it)
So USB-C wouldn't affect weather proofing and I wouldn't worry about this.
As for the Canon and third party saga I guess it has been already widely discussed. FWIW the price of this lens is close to RF 85mmf2.0 IS macro and personally I wouldn't swap mine with this one, but this has nothing to do with Canon and third party offerings discussion.
