Agree about keeping hiking/climbing, it's a natural conversation starter and makes you look well-rounded.
I think #13 can go pretty unequivocally. I would pick one of #4/5, they are so similar, probably #5 because you actually travelled. I would pick one of #8/9, you fulfill leadership well with the VP slot.
But those are just the thoughts of one man, I hope you get a varied collection of opinions to help you make your choice!
