I'm sadly the last person to ask about careers! My guess though is that if you're undecided geography might offer better prospects as being more visibly relevant to international relations and business (history is of course also valuable for both, but I'm not sure it's widely perceived as such) - and of course an environmental component would be useful in our times. An environmental, economic & human geography mix incorporating change through time might be a way to go while you weigh up specialisation options.

You might be better off taking that query up with a geography subreddit or board (or some academics if you can get your hands on them), unless there are any hereabouts with experience of both fields. The whole world of work is a formidable challenge, and who knows where it's headed? In your favour at least the baby-boom intake is retiring from the scene and AI isn't yet smart enough to replace them. Good luck in whatever you choose.
