So now that I'm mostly working from home, I bought a Thunderbolt monitor, and the setup is actually pretty awesome. The montior has both USB-C and USB-A inputs. I've got a physical network cable plugged and my USB-A mechanical keyboard plugged into the monitor; and of course the monitor also acts as a charger for the laptop.

Boom -- instant docking station: Plugging in a single standard cable gives me power, ethernet, monitor, and external keyboard.

Obviously you have to carry around a USB-C adapter when actually traveling, but if you get a good all-in-one adapter that does ethernet, HDMI, and USB-A, I haven't found it too disruptive. Hopefully the USB-C form factor will take over and then stay as long as USB-A has.
