Ubuntu Live distro would be a good place to check your Bluetooth and Wifi card, you don't even need to fully install it, just use the Live Distro to see if it activates your BT/Wifi. So no need to install a spare hard drive for Ubuntu.
I'm not sure if you can get your BCM94322MC card to work in Mojave, some of the older Broadcom cards were dropped when Sierra was released (kexts no longer within IO80211Family.kext Plugins), your card is not listed but all the others are from the same family, i.e. BCM9432X cards, see https://www.tonymacx86.com/threads/...i-devices-unsupported-in-macos-sierra.201746/
Also you would need a PCI-E adapter card for this card to work, as it will not work in the M.2 slot.
If you are going to go that far you might as well buy a pre-loaded card such as this one - https://amazon.co.uk/Bluetooth-PCI-...920&sr=8-3&keywords=hackintosh+wifi+bluetooth.
Installing a card such as this would mean you won't have anywhere to place a GFX card, with your ITX board only having one PCI-E slot, if you should decide you want a GFX card in the future.
