OptiPlex 5090 SFF adding Bluetooth and wi-fi

We have a few OptiPlex 5090 SFF being adapted to work from home use. Some of our employees want Bluetooth for wireless keyboards and mice, and wi-fi for home office set ups without access to ethernet connections.

What options do we have for adding Bluetooth and wi-fi. Do external usb wi-fi usually include Bluetooth, or do we need to add wireless cards with Bluetooth and wi-fi.
