But with Qobuz, you can currently stream 24-bit/48 kHz audio from the Sonos app which is a good sign this will more than likely be possible with Apple Lossless too.

But Apple Hi-Res Lossless will probably not be supported on Sonos speakers.
Currently Apple Spatial Audio/Dolby Atmos music can only be played from the Apple Music app on the Apple TV 4K to the Sonos Arc using a TV with HDMI eARC or the HDFury Arcana. The Sonos Arc is the only Sonos speaker that supports Dolby Atmos audio.
