New to Console Gaming: do I need a Xbox Live Gold or Ultimate if I only like single player games?

Do I need a Xbox Live Gold or Ultimate subscription if I only like single player games? When I bought my Xbox One it came with a limited time subscription of Ultimate but now it's costing me money and I'm not sure if I really need it. Is there any advantage to keeping the Gold or Ultimate subscriptions in the way of saving games or storage in the cloud? I really appreciate any input. Thanks!
