The easiest types of colors are the ones with little or no pattern, because then you don't have to start worrying about "What if this little section here is wrong...?" or "I don't think that part is supposed to have that coloring.", etc. You'd have less to worry about if you stick with blacks and blues and whites, in my limited opinion, because if there are any faults at all, it wouldn't be hard to tell. And if not, that's one less thing to be worried about.
I've heard that Cochins are easy to handle and show. I'd personally go with bantams for exhibiting because I naturally, for my age, have small hands and find it much easier to handle a bantam bird and not worry about them getting flustered and jumping away. Also, they're easier to keep (eat less, less messes), and I have a built-in love for 'everything smaller'.
I personally don't see it as a con but people tend to complain about bantams because they lay smaller eggs than those of their large fowl counterparts. If you really want bigger birds aslo, perhaps divide the coop.
