We have tons of short courses from great providers. My favorite is one which pairs teenagers like your daughter 1:1 with a postdoc at Cambridge University on a two week project e.g. creating an AI for categorizing blog posts. At the end of the two weeks your daughter gets a reference from that same postdoc on their enthusiasm, aptitude and preparedness for that technical subject. You find that if you and your daughter go through 2 or 3 such programs together the process of selecting among them and the references you get from academics give you a ton of context that genuinely prepares you both for the bewildering world of technical professional and academic careers.
Last year I remember in particular we helped one kid navigate the maze of "Computer Science vs Videogame Design vs Computer Art vs Chemical Engineering" this exact way. It was great to see his parents learn all about the nuances of the videogame business and careers in CS despite having a Chemical Engineering background.
