Hiya!
I graduated in 2024, and studied the BA in History at Durham, and I was in a fairly similar position to you when applying for undergrad (that being, I knew I wanted to apply for Durham, and that if I got in it would be my top choice).
Durham offers historians a HUGE range of modules, many of which are cutting edge and often times a bit weird to outsiders. For instance in second year I took a short fat module on early modern hospitality in global comparative perspective which has since influenced the course of my postgraduate study! Within these modules you're offered a huge range of customisation as usually you will have a long list of essay questions and topics to study, and some professors will allow you to develop your own essay titles for their modules (I was able to do this in my third year special subject and it was one of the best essays I've ever written).
You'll get the opportunity to study all different kinds of time periods, and countries, through all kinds of angles that you may not have considered before (I believe they currently have an module on an animal history of South Asia, for instance). I've reflected a lot on my academic experience there this year, and can honestly say that it was worth it for me. I would not be on the trajectory I'm on if not for the level of customisation on offer at Durham. I can also say that most of the history faculty are lovely people who want the best for their students, and it really is a place that encourages your individual academic development.
Even though it is a stressful programme, it is SO FUN. A particular highlight for me was the special subject in third year, which really hones in on source analysis and allows you to really dig deep into a specific area of history. Though I cant say it was a 100% positive experience, and there are some problems that become really apparent when you're a student (slow admin, housing/accommodation is a real pain) there are problems with every university, and on balance for me it was worth it! Durham also has a great careers service, which you get lifelong access to as an alumni (which is not something offered by many universities) and has fantastic resources for history, particularly in terms of what's on offer digitally through the library (side note that the arts and humanities librarian, Dr Richard Pears, is great and really helpful).
I was at Hild Bede, and while I would recommend it, just bear in mind they have been relocated as the original site is undergoing development. However, all the staff are lovely (Simon, who is the college principle, is especially wonderful) and it is a really welcoming and inclusive environment.
In terms of admission, your grades are stellar (better than mine were lol) and you stand a good chance of getting in. I think what really helped me was showing I had thought deeply about the subject (e.g. criticising or reflecting on the work of a historian) and suggesting at what you might like to study at Durham. If you have a particular period or angle that you'd like to work on (for me this was medieval history, though I ended up specialising in late modern, so you don't have to stick to it) mention that and talk about what it is that interests you, and what work you've already done within that period (an EPQ, A-Level module, books you've read, museums you've visited, lectures you've watched).
Mentioning books or academic articles you've read is especially useful (a professor at Cambridge once told me at undergrad they don't really care about podcasts, as they're assessing your ability to engage with an academic text, though I think Durham are less intense about it don't put things like moocs and podcasts as your primary evidence of engagement with the subject).
Ultimately, what uni is best for you is going to be dependent on what that university can offer you. Don't worry about becoming a rich and famous historian at this stage: the landscape of HE is ever changing, and the current moment is witnessing huge changes to PhD funding in the arts and humanities so it may well look very different if you get to the point of applying for postgraduate courses in history in four or five years time.
I wish you the best of luck, and I hope that was helpful.
