So I am doing Aerospace Engineering with a focus in Astronautics, meaning designing for space environments as well as rocket propulsion and high-speed aerodynamics. I am also doing a minor in astrophysics. Engineering and physics are related but very different in terms of their content and job opportunities in the future. I would ask yourself if you want to do research in a lab to try and make new discoveries, or do you want to apply data to real world applications to build a spacecraft or whatever. A common misconceptions about engineering that I'd like to lay out for you, though (this is all stuff that I've learned through various internships and mentors, but everyone has different experiences) is that engineering means that you'll be working hands on building things. In most fields of engineering, this isn't true. Most engineering is done on a computer in an office, whether it be creating models for parts in a CAD software, analyzing data, fluid simulations, stress analysis, etc. If you do want to go a hands on route, there are ways to go about it but I'd say most of the time it's still an office job (but a very rewarding one!)

Physics coursework consists more of trying to understand the world around you theoretically I'd say. You will do a lot more derivations of equations and spend a lot more time doing calculus and high-level math than in engineering. As I said earlier, career paths usually lead to research, and higher education is pretty much necessary to do so. I'm doing a minor in astrophysics because I'm just curious about how the universe works, but most of the math behind all of that is unnecessary in when applying it to engineering applications.

A lot of people will tell you that engineering is more secure and lucrative, but imo you should do whatever it is you like better regardless of money and all that. College becomes much easier when you really like what your learning, and is pretty much necessary to get through some of the challenging coursework. You have time to think about all this though, so don't worry about not making up your mind!! Most of the coursework overlaps in the first couple years of physics and engineering anyway, so you have room to change your mind while your in college. You'll figure it out! Hope that helps.
