It makes way less difference to the sound than most people think. In a blind test with different string gauges, I think few people would be able to tell which is which.
Also be aware that changing string gauge also changes the tension. You will need to readjust intonation, spring tension (unless you have a fixed bridge), and possibly truss rod.
For a beginner, I would highly recommend sticking with the standard 10-46. Aside from the adjustments needed, heavier strings are also a bit harder to play. Even as an experience player, I find zero benefit of heavier gauges.
