Only thing I'd have preferred is a tweak to the last line. Rey responding happily with either "no one" or "Just Rey" instead of "Rey Skywalker"
Fits her arc better imo
I like to think that Skywalker could have been the name of the method or organization or whatever that Rey uses to distribute the Jedi texts across the galaxy. Something like that would have been a nice way to compliment the previous film's ending scene, I think. Last Jedi ended by saying that anyone could be Force capable; that it didn't just belong to an elite group of knights or a couple of gross baddies. So Rise of Skywalker ends by completely democratizing the knowledge and wisdom that goes along with it; figuratively rising from her possession to walk through the sky to reach the people, never to be suppressed again. A bit heavy handed and perhaps a little ironic, but I like it, and it definitely says something great, which is a much better way to end a 42 year story than saying not much at all. Instead, its just a name Rey takes for herself, which says something, but its less interesting, I think. Oh well.
