Looks like Thunderbolt is not supported in either of the multiport adapters. That is disappointing. Perhaps Intel licensing fees were too high or something. I can't think of why they would eliminate it. Also neither of the adapters offer a second USB-C port.
Does the Apple store accept AMEX? What do you know? They Do. AMEX has lots of advantages, but most people including the rich have more than one credit card anyway. Personally, I don't leave home without it.
