I recently got the
Monoprice 60W 4-Port USB Smart Charger with USB-C and USB-A Ports and would definitely recommend it. It provides a full 60W over USB-C to charge the MacBook Pro, and while the 3 USB-A ports are limited to 2.4A total, that should be fine for overnight charging of the iPhones. Maybe two of these along with another "standard" Anker 4-port USB wall charger (or the Powercube linked above) should be sufficient for your watches and iPads as well?
