They’re probably launching this rocket from French Guiana because the launch pad is close to the equator. Maybe the telescope is going to a geosynchronous orbit.

No, it will be stationed very far away. I don’t think it’s a Legrange(?) point, but there will be no servicing opportunities. It has to work out of the box. Now its launch window starts at 7:20am Eastern Christmas morning, last I heard.

From https://www.nasa.gov/topics/universe/features/webb-l2.html

The Webb won't be orbiting the Earth –instead we will send it almost a million miles out into space to a place called "L2."

L2 is short-hand for the second Lagrange Point, a wonderful accident of gravity and orbital mechanics, and the perfect place to park the Webb telescope in space. There are five so-called "Lagrange Points" - areas where gravity from the sun and Earth balance the orbital motion of a satellite. Putting a spacecraft at any of these points allows it to stay in a fixed position relative to the Earth and sun with a minimal amount of energy needed for course correction.

You are correct.
