OpenBSD/arm64 on Apple hardware doesn't use firmware from bwfm-firmware,
there's some process to copy it from MacOS via the Asahi installer and
it's then picked up by the OpenBSD installer. (I'm not sure of all the
details, the only option for wifi on mine involves a chain of dongles).
But if it's not showing in dmesg at all, you're not at the point where
firmware would be used anyway.
dmesg might be useful if you've got some way to transport it (usb stick,
usb ethernet, etc)

Worth a try.
