What would be a good song for a beginner?

My friend wants me to teach her to play guitar. But see i've only been
playing for about two years and im not the teacher type but i am
willing to help her becuase i want to. What would be a good acoustic
song for a beginner? I was thinking Let It Be by The Beatles because
that's one of the first songs i ever learned. What do you think?
P.s. I know Let It Be isn't an acoustic song but i did an acoustic
cover.
