Help me choose

I would like to join some martial art clubs at my university.

Here are the ones i am interested in

Aikido
Brazilian Jiu-Jitsu
Ju Jitsu
Boxing
Muay Thai (Thai Boxing)

Obviously it's impossible to go for them all. What is a good combination? I want some striking + grappling combination.
