I’m not sure if I worded my question correctly, but let me try to explain more.
If we use a giant telescope to look at another planet 10 light years away from us, we would be looking at how it was 10 years ago. The thing I don’t understand is how does light store and also transfer all the information about that planet (or all the “data” that ends up in our eyes) and yet it’s still the fastest thing.

In very layman terms, information is stored as traceable changes in the properties of something. In this case, that “something” is light, and a property could be intensity. So it’s not that something is added on top of light. Rather, it’s just changing some property of light, which post detection, enables you to make inferences. The speed with which information travels is dependent on how fast you can transfer that “something”.
