How are these two ways of storing information handled internally in the engine?
What are the most common cases to use each of them?

Thank you for your time :)

Array and Dictionary are fundamental data structures in many development languages, so most non-Godot references to this question are still valid (FYI).

Anyway, an Array generally provides random access to a sequential set of data, whereas a Dictionary is used to map between a set of keys and a set of values (so, very useful in mapping random "pairs" of information).

Here's some additional context, but I'd encourage you to dig further...
