Fantasy
A dragon’s intelligence only matters if it changes the social temperature of the scene.
If it can speak, fine. That’s one problem. If it can understand but not speak, or speak badly, or choose not to, the story gets more interesting. The real question is whether anyone still dares to treat it like a beast when it clearly isn’t one. Or whether they keep doing it out of habit, which is usually where the trouble starts.
Fantasy sometimes spends too long on the dragon’s cleverness and not enough on the human embarrassment of realising they’ve been underestimating it for years.

The danger is usually in the bookkeeping, not the fire-breathing. If a dragon can read contracts, remember names, or notice when the “gift” table is being quietly looted, then the whole social order has to wobble a bit. That’s where the story lives. Otherwise you’ve just got a very large animal with better diction.
