i am not sure if i fully understand what you mean by unintended changes. if this means changes in the settings etc. you could use the events api, and check if new events on certain objects have been created
in the cloud environment, we do the upgrades of versions automatically, so this is something that can change aswell. you could monitor the version, if that helps you to see when exactly the version update has been made.

We actually have a solution scenario document for a SaaS product use case that you could take a look at as well as what Fabienne has already mentioned - Let me know your thoughts here or if you need more help: https://zitadel.com/docs/guides/solution-scenarios/saas
From a technical side we do not have specific implementations that warn you somehow, or where you can mark an instance as prod instance, to be extra careful.
