It's interesting that right now, MacPorts is further along the M1/Apple Silicon porting process than Homebrew. I think this is because Homebrew tries to do everything from a binary repository and MacPorts downloads source, patches it and builds it. Since a lot of the open source repositories have Apple/Darwin AArch64 ports now, it seems to work in most cases.
