Amazon is the best (and most confusing) place to buy these.
For USB-C hubs with multiple ports I know someone who is happy with the Juiced brand.
I find this category butt ugly and since I will never have more than one accessory connected at a time, I decided to
buy individual pieces.
USBc to USB 3.0 (nonda and syntech are nice looking, there have been some reports about nonda messing with 2.4 ghz wifi, so i got syn tech). 10 bucks for a 2-pack. Later i found a local store selling generic ones for 2 bucks a piece.....just goes to show the kind of markups in this category.....its s racket.
I also got a usb-c card reader and a couple of usb3 to usb-c adaptors.
All these are small and unobtrusive which i like.
