Personally if I were to go for an engineering degree to get into aerospace or aeronautical engineering, I would pick mechanical engineering instead of aerospace or aeronautical engineering. This is because the latter 2 are subdisciplines of the former. If you later decide aerospace isn't for you or decide to pivot outside of aerospace, it's probably easier with a degree in mechanical engineering.
In terms of meeting prerequisites, I think Pre-Calculus is a bit too simple for aerospace engineering degrees. Typically, the degree involves a lot of calculus.
See the following for AP in maths:
https://blog.collegeboard.org/what-ap-mathIf you look at the international entry requirements for each of the individual degrees, you would see that they require AP Physics and AP Calculus BC:

There are no aerospace engineering degrees at Cardiff at the time of writing. See:
https://www.cardiff.ac.uk/engineering/courses/undergraduate/our-degree-programmeImperial only does degrees in aeronautical engineering as opposed to aerospace engineering:
https://www.imperial.ac.uk/study/subjects/aerospace-engineering/#d.en.1200061Entry requirements for the above degree though are 5, 5, 5, 5 overall, to include:

In terms of universities offering aerospace engineering, my go to tends to be the Guardian League table:
https://www.theguardian.com/education/ng-interactive/2024/sep/07/best-uk-universities-for-aerospace-engineering-league-tableOther unis that are close to South Wales include Bath, Bristol, UWE, and South Wales.
Other university league tables include:
https://www.thecompleteuniversityguide.co.uk/league-tables/rankings/aeronautical-and-aerospace-engineeringhttps://www.thetimes.com/uk-university-rankings/league-table (might need subscription)
Having said that, I would take the rankings with a pinch of salt; they aren't always effective indications of how good a uni is relative to another. It's just not likely the league tables are so bad that unis at the bottom of the table are mistaken as the unis that should be at the top.
The leagues tables are good in the sense you get all of the degrees from all unis in one place so it saves you googling for them.
In terms of conversions, it's difficult to find anything consistent. Ultimately, it's up to the individual unis to decide whether they accept you and they in turn have their own set of conversion table.
For most unis, they have their own interpretation of what grades you should have, and that would be my starting point if I was in your position (many of them have their own AP grade requirements listed on their course pages as I have pointed out above). See the following as examples:
