Firstly, congratulations on your offers!
Now, as a current A level student who is also looking to pursue cybersecurity, I believe that I can provide some guidance here (this isn't intended to sound condescending though the more I say this sentence in my head, the worse it sounds ☹️).
When I decided to apply for Computer Science in year 12 (2022 - 2023. Up till that point, I was unsure what I was going to do), I spoke to my Computer Science teacher whether it would be beneficial to apply for cybersecurity specifically or Computer Science. He told me that both have merit and neither will impact job prospects. The main factors that affect job prospects are your own employable skills and the university you studied at (i.e. how good is its reputation).
The only thing that he said was you can go for Computer Science and then specialise in cybersecurity and still get there and if you decide in the future that you don't like cybersecurity, you can switch to a different speciality. However, if you go with the cybersecurity degree program specifically, you limit yourself to the cybersecurity field and it is far harder to get a job in other fields, not to mention that when you apply for MSc or MTech programs, you will be limiting the focus of your degree to a further niche specialism in the cybersecurity field, which is considered to be a bit disadvantageous.
However, he said that if your heart is completely set on cybersecurity, you should go for cybersecurity. You will cover three years straight of cybersecurity and this will mean that you will have an enjoyable three years and look to get a job in cybersecurity and no other fields.
In the end, I have chosen to apply for Computer Science at all of my 5 universities. I applied to Cambridge, Imperial, Edinburgh, Manchester and Durham. I have received offers from Imperial, Edinburgh and Manchester, I got rejected pre-interview from Cambridge and waiting on Durham.
I hope this helped
