The Behringer will be your best bet, I doubt you could get a FireWire interface working on a brand new Mac.
I've got an old Mackie onyx firewire interface working just fine with a just pre m1 2020 Mac mini. Had to use two adaptors but works flawlessly.
Good to know. From what I've read it was High Sierra that killed off the FW Duet but I haven't actually tried.
