I'd recommend you get her a pair with an AG (artificial grass) soleplate. They have all conical studs and are less likely to get hung up in the turf.
My personal favorites right now are the tiempo legend 6 if you're looking for a more classic kangaroo leather boot but that's still thin and light like a more modern soccer shoe or the hypervenom phantom 3s (low cut). Both come in AG variations and are nice. The hypervenoms have a real nice sock like fit but are a little tough to get in and out of (I have a pair of the tech craft ones). The tiempos run about half a size small and have sole separation issues but are also very nice and you can send them back to Nike if you have issues. Both shoes are one piece construction which I really like (no tongue getting bunched up or sliding to the sides).
Below those you can look at fg shoes with all conical studs like a Nike premier or Copa mundial (or anything else with a similar stud pattern). That being said, it's most important that the boots fit and feel good, I'd just stay away from anything with bladed cleats, without laces, or with collars.
A good resource that I use for gear info is soccerreviewsforyou.com the guy has a really good YouTube channel where he talks about all the new stuff.
Also soccer.com has a sale running now 15% off boots over $99, so it's a decent time to buy.
Hopefully that helps
