Wifi/Bluetooth m.2 with best Bluetooth support?

I'm looking to get a Gigabyte Z370N WIFI board that lists its Bluetooth compatibility thusly:

BLUETOOTH 4.2, 4.1, BLE, 4.0, 3.0, 2.1+EDR

This seems like better support than the Broadcom m.2 cards I am to plug in for Mac compatibility. Since the Bluetooth is more important to me than the Wifi, should I just disable (or ignore?) the Wifi and use the Bluetooth that comes with this board, or is there a m.2 board that offers the Broadcom chipset as well as the latest Bluetooth support?

I'm hoping to use this machine for Mac and Windows, and it needs to last a while.
