>the latter will drive you more to banks, economic institutions, insurance, government contractors, exchanges and similar jobs.
I worked for a gov't subcontractor (for the USAF) and a bank prior to moving to the bay and working at a FAANG. The opportunities to make 500k+/year don't exist, outside a few private funds that grind you to dust. If you are super well connected and you can start a military contract firm, you can make tons of money, but that has nothing to do with things you'd learn in a CS + X double major. Think tanks and other economic agencies don't compare with a good FAANG salary. You'll start at 50k and be lucky to make 200k by the end. 200k is a starting salary for a facebook engineer in most markets. I have two friends who are engineers at insurance cos, they certainly don't work there for the money.
If you're talking about jobs that don't involve CS applications, I wouldn't have any idea, but this isn't what OP was asking about.
Not everyone picks a job based one what "fulfills" them. Some people are trying to pay down college debt, support a family, support a lifestyle etc. And if what fulfills you working with very smart and driven individuals on very difficult and ambiguous problems, I think you'll enjoy working for a large tech company.
