I would like some pop girl song suggestions for a project

Hi friends. Next year is my last year of school and, I'm going to have a presentation night to present my capstone to my class, teacher and parents. Another thing I need to do is create a baby video and I need to have a song to play alongside. I love listening to pop girls but I don't know which songs would be good for this project.

My teacher said that I need to use songs that would be deemed school appropriate. The only song I can think of that would be suitable for this project is younger you by Miley Cyrus (for the Hannah Montana 20th anniversary special). I like how reflective the song is. If my teacher doesn't approve of this song (which is probaly unlikely) or someone else uses this, what are some pop girl song suggestions I could use for my video.
