Y13 here so hopefully this expertise should be relevant enough,
But if you're interested in creative subjects I'd say Art - HOWEVER some schools (depending on if yours does it or not), also offer a Photography course that's said to be highly creative if you're interested in that route. What many people don't talk about for creativity is the option to do an E. P. Q, or Extended Personal Qualification. What that's essentially about is that you spend two years researching a topic you're passionate about and producing a piece of work by the end of it with a step-by-step process of how you got from start to finish for the entire thing, so that could be one. I know for mine I'm doing something on Mythology and it's so fun, so you can choose what you're interested in. Warning: the E.P.Q is worth only half an A-level (no clue how that works) but it does help you get into Uni easier as it displays your knowledge of skills you'd use in day-to-day uni life.
For writing, I'd recommend English Literature - and before you say it, it's nothing like GCSE Literature. I know for A Level you are still required to study poems, plays and books but the questions in the exam are more generic based (meaning they give you a prompt saying how this theme is conveyed or this character is portrayed or those How far do you agree questions, and for those you can write about literally ANYTHING!) Even better is that for P2, aside from the Unseen Section A, you get to choose what texts you want to use to answer the questions for the rest of the paper, instead of sticking to a whole 'I need to use this play for this section because the question says'. Literature, in my humble experience, also allows you the option of more creativity though use of the coursework element where you use the critical lenses to evaluate a novel and play of your choosing. However, for the poetry coursework you can write your own poem in the style of a chosen poet and write a short evaluation of what critical lenses you wanted to show through your poem, so that also links with the creativity aspect in a way.
For visual arts, you can either choose an A-level in Media studies or Drama (HIGHLY RECOMMEND). I don't know much about Media A-Level but I do know that for Drama, you still have your same exams as GCSE, only more in detail, however you work in a smaller group and are there with people who actually want to be there instead of those GCSE students who took it for a doss and you never got any work done.
For History - YES ABSOLUTELY GO FOR IT! It's harder than GCSE sure, with you having to learn loads more but that's A-Level for you. Even better, you get tasked with writing a coursework just like Literature and E. P. Q where you evaluate a historical period you love and evaluate it like you'd see in a history book written by a professional historian, so that's cool.
Hope this helps!
