Decent quality optical media don’t need laboratory controlled conditions to be stored in. They will store well in most environments and last without problem at least 10 years - just avoid exposing them on direct sun/UV light.

You are focused on finding the ultimate media that you will record once and forget about it for the next 50-100 years, from a manufacturer that will guarantee you that you will be able to retrieve your data after xxx years when you need it. Unfortunately no such media exist. Focus on what optical media is brilliant at: you can predict when it will fail before it fails. In other words learn how to scan media and interpret the results and determine when it is time to migrate your data.
