You really need to think about what you may want to do after A-levels - this will help inform your A-level choices now.
In general, Maths is a good choice, but if you are considering taking Physics you more or less are necessarily required to take them together. Every course that requires A-level Physics will also require Maths, so taking the pair ensures you can actually apply to these courses. Maths is also very recommended if you think you may pursue economics at uni, even if you don't take A-level Economics.
Of the remaining A-levels, the only one which is a required prequisite to any course is Spanish, which is necessary for any Spanish language degrees (including joint honours courses with Spanish, usually). However according to TSR, language A-levels tend to be pretty challenging for even very able linguists - unless you have an exceptionally strong background and interest in language learning and linguistics, it's probably not the best option.
The others are generally good essay based A-levels, and are all more or less accepted equally. Taking the relevant subject at A-level may help you decide if you want to pursue it at degree level, so these could all be used to explore a subject area. However there is the caveat that some A-level subjects don't reflect the study of that subject at university as well as others.
A way to help you decide which you want to take is think about your GCSE studies and exams. Which aspects of the subjects that you've taken which are on the list you provided did you enjoy? Which didn't you enjoy? Are there are any general exam types/styles which you find more difficult or stressful, e.g. oral exams? In language A-levels you'll need to be pretty comfortable talking in class, both presenting and in roleplay discussions, as well as giving oral examinations. If these are things you tend to not prefer, I'd advise not to pursue that route. Similarly, for Physics there will be a signifcant lab component; if you didn't like doing circuits/electronics in GCSE Science, or writing lab reports on a regular basis, you may get fed up with that subject. Maths is fairly self-explanatory - you'll probably have problem sets very often (weekly potentially), and you need to keep on top of it or else you can fall behind pretty quickly as much of the material builds on the earlier content.
The other subjects are essay subjects - do you enjoy writing extended academic prose? You'll likely have pretty regular essay deadlines for these subjects, particularly if you take more than one. If the thought of having to write 2-3 essays or projects often fills you with dread, or if you find yourself panicking at the start of essay exams where you don't have all the material with you or a specific essay plan already set up for that particular title, you might struggle. On the latter note, while you'll generally prepare "generalist" essay plans ahead of exams, you can't necessarily know what questions will come up - so you need to be able to change tack pretty quickly. Also, while they generally aren't "long form" essays in exams, you need to be able to fit a lot of factual information into relatively short chunks of writing/time for those subjects.
So, basically - if you take physics, also take maths. If you take economics you should probably take maths as well, as many economics courses at university prefer or require maths. Make sure you know what you're getting in for if you pick spanish and be prepared to put in a lot of work for it. For the other essay subjects, be aware that they may not necessarily be representative of university study in those subjects, nor are the specifically required for it - make sure you choose the ones you're genuinely interested in, rather than ones that will "look better on paper" for a given course/university.
