Good luck with whichever system you decide to replace Sonos with.
This hasn’t been possible since august 2019. If you really want to keep playing music form an iOS-device you need Airplay. Apple made playing from an iOS-device impossible around the time they introduced Airplay 2 (not only for Sonos by the way). The only reasonable solution for the problem Apple seems to have caused is to buy a One (SL) or Ikea Symfonisk, Airplay to that and group it with your older speakers.
Yes this means you’d have to invest in an extra speaker, but it will breathe new life in to your existing speakers.
