Home theater/audio question - new construction

I’m in the process of designing a new home theater/audio system well in advance of drywall. I’ll be doing all low voltage (cameras, cat6 drops, coax, etc.) myself, but I’m way out of date on home theater/audio design. The floor plan contains an open concept living, kitchen, and dining with a TV and media cabinet in the living. The back patio will also have a TV and be used for entertaining. I’d like to keep the speakers discrete with the exception of a soundbar if the soundbar can provide quality sound and replace multiple speakers. Here is what I’m thinking - please provide feedback if you don’t mind. Living: Sonos Arc, Sonos sub, x2 Sonance in-ceiling behind seating area. Kitchen: x2 Sonance in-ceiling. Back patio: Sonos Ray, Sonos 100/roam/or move(to expand range/flexibility of TV or music via TV). I’m guessing I would need a Sonos amp in the living and outdoor patio and would have two separate zones? Or can I connect a 100/move/roam directly to the outdoor soundbar without an amp? Movable speaker will always mirror the soundbar. The kitchen speakers are primarily for music but could I just put them on the same channel as my in-ceiling living speakers to avoid needing a separate amp? I’ll always play living and kitchen speakers together (TV or music). Wiring is no problem. Sonos just seems appealing due to the simple interface and controls. Our area does rely on cellular internet, so WiFi could be spotty at times. I will have a home network with PoE switch though. Appreciate any guidance yall can provide.
