GCSEs are more of just a step to A Levels, I don't think it may matter that much, provided that the field you want to enter in the future (i.e Computer Science, etc) isn't part of the option.
Let me say straight off the bat, Unis REALLY don't care if you have the Ebacc, don't do it for that reason, do it because you enjoy the subject.
I personally took French, Geography, and Computing for my GCSEs. I absolutely hated French, however if you gel naturally to languages, then I say go for it! Humanities are always a good way to round up your GCSEs so you get a good spread of different subjects, History or Geography, dependant on preference.
At the end of the day, unless you intend on going to Oxbridge, the GCSEs don't matter as much, of course, try your absolute best, but remember they're just really needed in order to help you get to A Level.
