Admittedly, I just use Sonos myself. However, I do hope to one day move to something else more open.
BluOS is another solution to look at. It’s still pricey, but works offline and higher quality than Sonos if you’re someone who has lots of high res music files.
Can’t vouch for it, but looks interesting and according to the GitHub is still being updated so worth a look if you don’t mind putting in some work and tinkering.

If you want something that’s more open, but way more DIY, I found this blog post that talks about a solution using Mopidy server: https://blog.platypush.tech/article/Build-your-open-source-multi-room-and-multi-provider-sound-server-with-Platypush-Mopidy-and-Snapcast
