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.

Information doesn’t weigh anything. Also, light isn’t the fastest thing. It’s very close but in most cases, it’s not even moving at the speed of light.
The “speed of light” is just what we called the universal speed limit because light was the first thing that appeared to move around that speed. But more realistically, it should be called the speed of causality. Or just it’s variable C. Because light itself moves at a speed related to what medium it travels in. Light through water is much slower than light through space.
Things like gravity move at that universal limit. Always.
