I think you'll get an extremely general and possibly skewed sense of things reading the comments here. What field do you work in? I would find a professional peer who is experienced and can serve as a trusted mentor, this is really more of a 1-1 type conversation. Think like the CTO of your company, or something along those lines. Even a friend of a friend would be good.

My personal 2c is at that age super high level advice on "how to learn" is going to be more useful than "what programming language is best". A lot can change in 4 years and it's better to set your daughter up to succeed at building a solid base of knowledge that will be adaptable to whatever trend is popular 4 years, or even a decade out, rather than take even an extremely well informed person's guess as gospel.
