I taught guitar long ago and one of the most discouraging things I ever saw was young students playing poorly made guitars that were physically too big for them. Don't focus on the instrument at this point, focus on the teacher. Find a teacher you feel good about and enlist their aid in finding the right instrument to buy or lease. Interview the teacher the same way you would any other employee that you would trust your child to. They don't need to be a phenomenal player, they need to be a phenomenal teacher who will challenge your daughter to become the best musician she can be no matter what instrument she finally plays. Find someone who wants to teach music not just how to play songs on the bass. This can be a life changing choice for your daughter. She can take pride in herself with good guidance or she can feel like she missed something and failed with a poor teacher. Someone who can master music will have the dedication and anylitical skills to excell in other areas too. (By the way, don't underestimate the challenges of learning music. The classes for my music degree were far more difficult than those for my management degree)
