Netplan can match interface by MAC address. Like

...
  ethernets:
    bridge-port:
      match:
        macaddress: 00:9d:d8:aa:66:19
      dhcp4: no
...
  bridges:
    bridge0:
...
      interfaces:
        - bridge-port

The interface ID (bridge-port in this case) must be unique in the configuration but otherwise can be anything. It is custom to use the interface name for the interface ID but it is not mandatory.
