How big is the room? How far are side walls from viewing position? How far is the back wall from the viewing position? Is Atmos desirable? Have you done any of your own research into Sonos products? What’s your budget? Why are you configuring with 100’s rather than 300’s? Have you listened to any systems and setups?
Way too many unknowns for a user community to comment sensibly, IMHO. You might get opinions but you’ll need to treat them with caution.
