We use variables primarily for things like product names and other short strings that occur in broadly shared content on the one hand, and have a different value in different contexts on the other hand.

Apart from short strings, we also have a topic link as a variable, to point to each product's specific instance of a certain topic.

Although everyone's free to make variables, most are centrally managed, exactly because they are typically cross-product items.
