I write with my left hand but play guitar right-handed. I don't think it had any effect on my playing, because I think I'm a naturally right-handed guitar player. Here's a list of things and whether I do them right- or left-handed:

Basically, the only reason I call myself left-handed is because I write with my left hand. All in all, I have no idea if I do more things left handed or right handed.

I'm similar. I do very little with both hands, but I'm split between left and right on individual things. Throw is right, write is left. Where I especially get hung up is learning something to do with feet - surfing, skateboarding, snowboarding, etc... I struggle to figure out which one is my preference. I usually find that I'm equally bad at both.

Our sports teacher in high-school would tell us to stand straight. Then he would shove us from the back a few times. The foot we would stop ourselves from falling would be our leading foot (for snowboarding). So if you catch your fall with your left foot, you're regular. Otherwise goofy. Don't know if that's a safe bet, but it seemed to work out for us back then.

OTOH: I am convinced I can't snap my fingers with my right hand and never will because my specific mix of handed-ness makes it impossible for me to do so, no matter how hard I try and practice. No problem at all with my left hand.

Our track coach would do the same thing! And he got really frustrated with me because the foot that I led with seemed to vary by day. I'd be fairly consistent on any given day, but another day I'd be consistently the other foot.
