As a "beginner", any "entry level" ball would be fine. I personally only have Roto equipment, and the Shout seems like it would be a great start. The ball is stronger than it would seem per the specs, but cover is easily adjusted.

I would suggest that she go fingertip, and learn with proper coaching.

I use the Shout a lot in leagues, but had to add a touch more polish to "tame" it for me.

You can look into any manufacturers line-up and basically choose a lower price ball and it should fit the bill in getting her started.
