and let her make her decision based on funding herself. Help her understand what debt is and go through some Finance lessons to understand what she's going to need to do with her decision. You can even go as far as look at average starting salaries for her best-guess major to extrapolate whether she can handle the debt load and why it's not as overwhelming as it probably looks to a HS student.

Then, you can jump in and pay for some/all of the schooling later and not only will she appreciate any help at all, she'll understand what you've done and made a wise, informed choice on her own.
