I would recommend staying with something very similar to what she is already swinging. When she gets bigger, stronger, better swing she can explore more options.
What she is swinging right now is a “very” balanced bat. Any Demarini CF, a LS LXT or Mizuno Power Carbon in 30” would probably be a good fit. I would look for a used one honestly.
My 10 year old DD is 5'3, 130ish. She swings the Power Carbon 32/22 and does very well with it. I might have her try out a few different bats to see if she likes one better
