But this has nothing to do with the question.

Moons and planets have a far smaller size to distant ratio than galaxies.

A galaxy may be a billion light years away but it’s 100,00 light years across. As something in our solar system my be a billion kms away but only thousands of kilometers across.

So just because it’s closer doesn’t mean it’s more resolvable.

I made a second comment where I addressed that. The JWST is designed to look for galaxies over 13 billion years old. GN-z11 is only estimated to be 4000 light years. It's actually a pretty similar size to distance scale as Titan is from the Earth. The amount of infrared light from the subject is also relevant.
