The firmware loads ok, see the last line in the log excerpt:

[ 1.649158] brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4378/3 wl0: Feb 8 2022 01:44:45 version 18.60.21.0.7.8.126 FWID 01-1cdae627

The failed firmware loads are for specialized firmware variants which might exists but in this case don't exists. See how they lose a part of their filename.

So Wi-Fi should work. Can you connect to an unsecure network? How is the network secured you're trying to connect to?

I'm getting the same warnings:
