Need reviews on my University list and a few suggestions

You can’t apply to both Oxford and Cambridge in the same year fyi

Oxbridge deadlines are 3 months earlier (oct. 15) and you can only choose to apply to either oxford or Cambridge. Not both.

Don’t know whether you can apply for the rest with the usual deadline (jan. 15) or with your Oxbridge application, you’ll have to check.

The UCAS application only lets you write one general essay. This essay is your opportunity to showcase your passion and dedication for the subject you are applying to. While it's possible to showcase a passion for both finance and economics, it's tough to do both effectively. By trying, you'd be missing out on the opportunity to show a full passion for one or the other and just come off as sort of "half-assing" two things. To each their own, but imo economics is fascinating to study and obviously there's a lot of overlap between economics and finance, so you're not really missing out on a whole lot. My personal suggestion is to go after economics as a subject, since the prestige factor is heavy and you can still study finance to your heart's content. Try taking an econ course online or reading an econ book just to see if you're into it before making a decision. My personal suggestion would be to apply to econ programs tho at all the unis.

Like another poster suggested, you have to pick between Ox and Cam, so you're down to 3. I would go with Ox/Cam, LSE, UCL/Warwick (UCL is stronger and more prestigious imo), and then 2 others. So that puts you at 3 risky unis, which isn't that bad tbh. And you still have a fallback plan (applying around the UAE/Middle East, so you can probably even take on the risk of 4 good unis, but 3 is definitely a minimum here imo).

Bocconi and Rotterdam aren't just nice, they're phenomenal. But I'm assuming you don't have a strong foundation in Italian or Dutch, so the experience just isn't going to be that phenomenal for you.

Yes, I meant Liverpool, Queen Mary, etc as being less risky but still Russell group so not awful either.

As you don't really want to be in London, you could do LSE/Oxbridge, Warwick, Durham/Bristol, Manchester/Nottingham, then whatever easy one you want as a backup.

For Durham vs Bristol, Durham tries to follow Oxbridge socially, quite a few posh students, and basically everyone's an Oxbridge reject. Bristol is more down to Earth and in an actual city. Durham is kind of like Cambridge in the sense that it's a university with a city, whereas Oxford and Bristol are cities with a university if that makes sense.

Manchester vs Nottingham, academically not a huge difference. I would opt for Manchester out of the two because the city has more going on, it's a very student focused city (3 fairly large universities, big night scene, easy to get around etc), and because you'll be going abroad, everyone knows Manchester because of the football clubs so it gives you something to talk about with basically everyone.
