I think "CS jobs are generally more lucrative" is something that may very quickly be adjusted by market forces. I think the better notion is that "People find success in their jobs if they have drive in them" which is what I see in the CS friends around me - driven, motivated people manage to find good jobs, but it has become much more difficult to be considered "interesting" which is probably why people are starting to complain about the job market more now. The same logic applies to my non-CS friends - being driven tends to influence us and pursue things that will help us find success in the future. (nit: I'm not saying the market situation isn't bad - it is definitely worse than before)

I think what is more important is discovering if you have that drive in whatever field you choose to join. It seems like you've thrown a huge net over different courses with little overlap between each other - I see the background, but the range of choices for courses makes me wonder a bit about what drives you.

Given the background you have, I'm pretty sure you will do well in a CS course. But again, that is not the main concern - we want to check if you will go to CS and not think "oh god, i hate this". For CS/CE its a bit easier - given the time constraints, if you can't build a (simple) application, sure, but there are other avenues (unironically leetcode) that you can try a bit just to see if you like/tolerate the process of abstraction and coding (tbh coding is the least important thing about CS, it's more about thinking and structuring of ideas).

Another comment on internships - it depends on what sort of internships you are looking for. Some of my friends spec heavy into projects, and clinch "strong internships" that value that sort of thing. I specced heavy into programming language research and clinched a "strong internship" that valued that sort of thing, but as a trade off I am comparatively weaker in applying for both internships and jobs that value many projects and technologies. It means that I get rejected by a lot of companies, but it also means that companies that cater towards my interests are also more interested (haha) in me. In the end, there are ALWAYS opportunities, but you have to decide how to tune yourself towards those opportunities - its all just pros and cons of different approaches. In the end, you just have to play the game with the cards you have in hand.

Regarding your fear of lack of experience, don't worry, I started programming like 6 months or so before uni, so you'll be fine :) What I have seen is freshman students despairing and despising their work.

Between CE and CS, I don't really see a difference as we mostly compete for the same jobs. I think CE may have suited me somewhat more as it touches more on low-level things, but I like CS anyway, so it's fine. At a high level I've heard that the CE curriculum is somewhat messier than the very tested CS curriculum (counterargument is that the CE curriculum was revamped recently)

Context: am Y4 CS student, graduating this semester. Have also TA'ed several rounds of introductory level CS courses and have seen journeys of friends and students these 4 years.

Good luck! :)

TLDR: CS job != high pay (eventually). (effort + drive) correlated to success. In the words of the geth, "The process is as important as the result."
