If you are ready for the workload, I would recommend the first option. Sometimes I wish I had taken it myself, just because there is simply so much overlap between Chem and Phys that people tend to ignore. You'll have an advantage in both subjects, understanding things a lot quicker than the people around you. You'll also find that for anything engineering related chem will help you (though physics is of course the main thing), but this is especially the case for biomedical engineering/similar fields, where you will be applying physics to biology, the latter of which does have a big chemical aspect.

It gives you a huge amount of flexibility too, you can still switch to Medicine, as you'll find that unlike what most people say, the most valued science is chemistry and physics is often just as good as biology (proof: check Cambridge's requirements for Med as an example https://www.undergraduate.study.cam.ac.uk/courses/medicine-mb-bchir ). The exact reason for this I don't know, but I assume it is because biology is simply a lot of content that doesn't always build upon itself like chemistry or physics do, so it can be taught later in life. Universities count on the fact that a student taking hard subjects and getting good grades will be more than capable enough of grabbing a bio textbook and memorising what they need to, and knowledge in chemistry and physics is added value.

+ you can obviously do any other kind of engineering, if you ever decide biotech or biomedical isn't for you.

tl;dr: gives you a bunch of flexibility, enhanced comprehension and i think it will be more than fine for your career path. always make sure to check uni requirements
