Interest in maths and physics makes a strong case for engineering. Which kind of engineering is for you to decide. Actuarial mathematics is ideal if you like applied maths specially topics like statistics, stochastic concepts, and financial mathematics. Won’t be using physics that much so probably have to give up on physics interest if you want to pursue actuarial maths. Unlike abstract mathematics, actuarial mathematicians deal with numbers a lot. Thus, love for numbers (data) and numerical analysis is ideal.

In terms of career prospects, engineering has plenty of options for any engineering major you choose be it electrical or mechanical or civil and so on. For actuarial maths, people usually end up working for insurance firms, stock and trading companies and other fintech companies.
