What’s the difference between UTC and Time Zone?

UTC, always. The “with time zone” phrase means “with attention paid to time zone”, not “store the time zone alongside this value”. The difference between the types is whether any time zone should be applied either during storage (INSERT or UPDATE) or retrieval (SELECT query).
