@darnsocks, if creative writing appeals to you then that’s a very good thing! Anything that truly piques your interest is important. Would it be too much to do an online language course over the summer as well ?..(an actual course to keep you working at it 
You seem very competent, with the ability to handle it, unless, of course, the creative writing class is intense. )
Sounds as if a small liberal arts college with strong teaching and lots of interactions with professors may be ideal for you, since that’s the common denominator for the classes you have liked.
I strongly suggest you check out St. John’s College (not Catholic) of Annapolis, MD and Santa Fe, NM. Very unique school with tiny seminar classes and strong interaction with professors…and emphasis on Greek, Latin and a Great Books of Western Civilization curriculum (and yes, that includes science.) I have known students who have loved it (but it’s not for everyone! Not if you want to pursue engineering, for example.)
If you take to creative writing, Kenyon College is notable for this, but also very selective. Check out the College of Wooster, Denison, Muhlenburg, Lafayette, Dickinson, Skidmore, Ithaca and Ursinus as well (for no particular reason, except that they seem to be nice, selective LACs for smart kids, that are not impossible to get into.)
