That's potentially quite a powerful mix of subjects, even if it is slightly off mainstream.
FWIW not knowing your job aspiration is fine (my School Yr 13 and Uni Yr2 children are the same) - what are you passions, what are you good at? Are there things you find easy that others struggle with?
If you are leaning towards sciences, as McGinger says, the biological / biomedical sciences offer lots of uni and career options. Many unis seem to like 2 A level sciences with something else, so you probably wouldn't be at any disadvantage. You could do IBMS Biomed Sci and work for the NHS, you could do Biological / Biomedical sciences and head in to research / academia. I can imagine CS skills would be pretty useful and relatively unusual - there are lots of computer intensive aspects of Bio research these days
If you are leaning to CS then that is pretty competitive and I am not sure if the sciences would help you, so I am guessing your extra curriculas could be useful there. Do you do any CS related things outside your A levels? Sort of related example, I was really interested in AI many years ago (80s) and had written conversational code (we would call them chatbots today) and adaptive / learning code (machine learning these days) and that was enough to swing me the offer of a sponsored degree in AI from IBM
If you havent already, I would encourage you to think about going to some uni open days this year to talk to folks, even to nearby unis you might not want to go to, but to explore subjects and choices - ideally go to one where you can speak with staff and students about lots of the taught subjects. Took my eldest to Exeter a few years ago, they had a massive hall full of staff/students covering every subject. We spoke with loads of different subject areas, she came away with lots of stuff crossed off her list (which was good) and really inspired to pursue economics, which wasn't even on her radar at that point
