Activate the connection in question, and then look for `GENERAL.HWADDR` in the output of `nmcli device show`. This represents the MAC address currently in use by the interface, whether randomized or not. It is also visible as "Hardware Address" (or similar) in NetworkManager GUIs under active connection details.

`<connection>` can be the connection name (usually the SSID for WiFi networks) or UUID, obtained from `nmcli c show [--active]`.
_Recall that these setting values are set based on the previous connection activation and take effect for the next connection activation._
