If I understood your problem correctly, you need to listen to Spotify through your HomePod which is on the same local network as your Mac.
This is what I do on macOS. I press on the little megaphone icon (enable it in OS sound preferences) in menu bar and then I can choose my HomePod from the list, without any third party software. I am running Big Sur but in two previous versions I also did the same. Maybe I’m missing something here but I think it should work seamlessly.
That routes all the audio from the mac though, not only Spotify. And with a noticeable delay.
This makes watching a "GIF" with audio (say browsing Reddit), opening a video, answering a slack call, etc. a very bad experience.
Spotify by itself supports its own protocol, whatever that may be, and chromecast. The iOS app should also support Airplay through the OS.
Personally I have a Spotify enabled receiver plugged to my audio system, it works really well.
