Judo or Wrestling combine with Boxing

Hi everyone, im looking for some great advice off some knowledgeable people.

I have been with my boxing (abc) club for many years. I would like to add something to it, to make it a well rounded skill set. I have been looking at Judo and wrestling, which would better the better option? I would like it to be easily transferred to deal with a realistic street scenario (not for sport)? Also what are the different variations of wrestling, Greco, Freestyle and Olympic? Which is best?

What are your thoughts about sambo?

Hope to hear from you all soon.
