One caveat with the MS wireless keyboards (with the dongle, since Bluetooth and I don't get along): the ergo MS keyboard I have had random connection issues with the normal Apple USB -> USB-C adapter which is required to plug it into my 15" tbMBP. I finally guessed that this is due to it being a USB2 devices plugged into a USB3 port. https://support.apple.com/kb/PH19094?locale=en_US https://support.apple.com/kb/PH19094?locale=en_US mentions this specifically, but briefly enough that it's easy to miss: """If the device is connected to a USB hub: Make sure the device and the hub are the same speed. Connect USB 3.0 SuperSpeed devices to a USB 3.0 SuperSpeed HUB, USB 2.0 Hi-Speed devices to a USB 2.0 Hi-Speed hub, and so on.""" I bought a cheap-ish Mac-specific (not that it should matter) powered USB 2.0 hub off Amazon. Plugged the kbd, mouse, and my HiFiMeDIY DAC into it. All now work well without nearly as many issues.
