Probably something like a clang-cross-compiler, or Linaro gcc-cross compiler, and then running unit tests in a raspberian qemu-static chroot.

or better yet just a debian /generic linux arm64 chroot (raspberry pi os formerly known as raspberian is just debian costumised to run better on the raspberry pi )

The point is to support this on github actions. None of the options you mentioned are currently available with github actions.

Please let me know if something like what i described is available though, as i'd be happy to adopt it.
