What to do?

[Dixiechicks2020]

So I’ve made it through the first year of raising chickens. I have 11 hens and one Speckled Sussex rooster who has started to attack me. I tried some of the techniques to get him to stop, staring him down and feeding him treats by hand, but he still runs after me when I’m in the yard. I found a new home for him, but I want to get another rooster that’s not aggressive toward me. Is it going to be okay to introduce a new rooster to my flock? I don’t want any of them to get hurt or injured. What breed of rooster should I look for and what should I expect when Introducing him to my hens?.

All chickens are individuals, so no one can say "x breed is nice but don't get Y".
Unless you plan on hatching eggs, there's really no need to have one.

Why are you wanting a rooster?
I don’t have my rooster to fertilize eggs just for protection of the flock while free ranging.... and of course I love a rooster’s crow.

I think this answers most of your questions. If you still have more, let me know.

What breed of rooster should I look for

One that meets your goals. For integration, breed is not important, get a rooster you'll like. What you want is a rooster that is mature. Get one at least a year old and probably not over two years old.
