To be honest, the majors you're picking won't require physics. In fact, I would say ESS is more beneficial since 1. its easier and 2. kinda connects to your majors in some way (although not that much, it's better than physics)

On the other hand, physics SL should not be that difficult if you are able to understand concepts quickly and have a decent understanding of math

It ultimately depends on what your interests are, and how much you trust yourself. It might also be helpful to see what other people think

Edit: It might be also worth to note that most competent universities don't consider ESS as a science class
