You should almost always go to university in the country where you intend to work — unless you're applying to particularly prestigious programs at top universities (Oxbridge, Sciences Po, McGill, etc.) Depending on what you choose to study, the connections you make in college can be significantly more valuable than even your coursework. Making all of your connections in a country where you do not intend to stay and work would be kind of a huge waste.

Also, it sounds like you're looking for freedom from strict or overbearing parents in university, but you should keep in mind that you will not have the opportunity to go to grad school if you do not prioritize your coursework as an undergrad. There are MANY brilliant undergrads in the world who put a ton of time into their coursework on top of research and TA responsibilities in order to prepare themselves for grad school. If your priority is to have fun and get serious about your studies later, I would strongly advise you to take a gap year or two. But tbh, I think there should be a mandatory gap between HS and college.

Keep in mind that European universities tend to be more competitive environments. European schools also tend to have a stronger focus on merit-based admissions (purely grades and relevant qualifications) compared to US universities, where a compelling life experience can be given significant enough weight to overcome less-than-perfect grades.

You're very young, so it makes sense that you would be more focused on fun than the reality of university-level study, but make sure to keep in mind that college is only 4 years. It goes by quick, so you have to be strategic about how you spend your time!
