I've had two roosters, both were unexpected additions to my flock, not planned. One was an Easter Egger rooster and was mean as a snake, although he was beautiful. A hawk got him. My current rooster is a buff laced polish with the top hat. He's an interesting addition to the flock, and so far has not proven to be human aggressive, although he is mean to one or two of my hens. I keep them separate from each other, so it works out in the end. I'd say that you really don't want a friendly rooster - sometimes those lose their fear of humans, and then in turn are prone to attack if they think you are trying to take over the flock. I did not handle my Buff Polish rooster as a chick, nor did I try to pick him up or cuddle him or feed him an abundance of treats. He got what the pullets got, and he views me as the bringer of food, for which he takes credit with the girls . I am hoping he continues in this way so that I don't have to cull him. I want to enjoy my flock, not worry about a rooster coming after me in the mistaken assumption that I am a threat or competition. You just have to pick and then pray that he's a good boy. I lucked out with the second one.
Had an EE rooster get mean a few years ago. Never again. Have two now. Buff laced Polish has been starting to be aggressive this spring. He tried that last year and a week getting water squirted at him solved that problem. When I get home next week I'll work on him. If he doesn't calm down he's history. My best rooster is a Salmon Faverolles. He's not friendly but is great with the girls and has never shown any aggression toward people as he avoids contact. He might be a bit too heavy for what you want.
Quite frankly, each rooster has a personality. Some breeds are know to be calmer but you can still get a mean rooster. When I was researching the roosters that were suggested are the Salmon Faverolles, Australorp, and the Orpington. All are probably larger than what you are looking to find.
