Thanks! The Dell is big and requires an external power supply, which is a no-go. The Cable Matters is better, but only does USB 2.0, which means I can't use it for hard drives. There's an HDMI version, but doesn't do 60Hz.

This is what I'm fighting right now. Lots of hubs, they all do some things right, but not everything. The reason is apparently answered by the first article ("any USB-C hub using this technique for 4K60 video can’t have any USB 3.1 ports on it").

I've yet to find a sub-$100 Thunderbolt dock. Monoprice had a sale on docks in December, bringing the price down to $56, but I was too slow to pull the trigger.
