Sonos will override Apple CarPlay

[tedk1980]

While listening to Spotify on Apple CarPlay. If someone at home runs Spotify thru Sonos then it will change songs on CarPlay while mobile.

This is correct behavior. Spotify can only be played on one device at a time, and if another device starts playing Spotify on the same account, playback will stop on the original device. Have whoever is using Spotify on your Sonos speaker use their own/another account to avoid this.
