The obvious and unhelpful answer would be one that you want to do. However...in the interests of being helpful...
You seem very interested in languages so something around that maybe. Interpreting, translation, speech and language therapy...all good ways to practically apply all the skills you’re gaining at A level.
But you could reasonably go into just about anything. Volunteering is a good way to find out what you’re interested in and the sort of work you like. Maybe have a look at do-it.org and see what’s available there.
