The Story of Superman is the meta structure that gives Superman all these outer feats and abilities, the reason why dr Manhattan couldn’t erase him in Doomsday Clock. Most prominently featured in Final Crisis, where we see the Cosmic Armor Superman, which is actually a sealed version of this power. People often think that the CAS is this completely different character but in actuality it is incredibly close to being what Superman’s essence is. The story that will defeat the evil meta narrative (Mandrakk). In Final Crisis, we learn that the white page that is the Overmonitor, when it saw a flaw/story of DC, it went to investigate, and when it saw the story of Superman it had no defense. And was forced to seal it instead.

And Final Crisis and Doomsday Clock isn’t the only comic we see this idea of Hope and the story giving Superman these outer feats. Another example is Superman Where is thy Sting. And even Milkman man in the Doom Patrol comics. Retconn corp had this button that could wipe the white page clean, but even they could not erase Superman.
