Oh! I had completely overlooked that paragraph.

I think I found a simpler method.

* Write the arm64.img to an SD card.
* mount the msdos ("EFI") partition
* unpack RPi4_UEFI_Firmware_v1.32.zip inside that

Then just boot from the SD card, and it works.

So it seems the arm64.img is just missing the UEFI files and newer
Raspberry 4 support files.

bwfm0 complained during boot:

bwfm0: Firmware file default:    brcmfmac43455-sdio.bin

bwfm0: autoconfiguration error: NVRAM file not available

I see no audio device in dmesg.

RAM is limited to 3GB by the UEFI bios for Linux compatibility - can I
remove that limit for NetBSD, or will it break?
