Hi Charlotte! Welcome. I live in a suburb housing tract in Southern California, below Los Angeles county. My city has the same ordinance - 5 hens max, and no roosters. So, I get it. For those of us keeping them as pets with benefits, I can attest that the number is not a deal breaker. Your list is great! I'd also recommend Black Australorps. They are prolific brown egg layers, super gorgeous, hearty, and, have become a favorite. I've also had Silkies, and that decision came before understanding what "being broody" meant, so while they are nutty little ding dongs, the broody thing is a total pain in the butt. We've become experts at spotting the signals and the broody jail accommodations are ready at any time.
Anyhow, we recently got 3 Easter Eggers. Talk about beautiful coloured eggs with prolific laying! Not sure which girl is producing which shade, but we've got lovely blue eggs, green eggs, and a green/tan. Most days we get 5 eggs, and as a family of five, it's more than we can go through daily. I've been sharing eggs with the ladies at our local senior center, and since most of them are on shoe string budgets, they are ever so grateful. And yes, I do sell to a neighbor as well.
Bottom line is, chickens are prey animals, so they have hard wiring instincts to be aware of, and some are more inclined to be flighty than others. Initially my Easter Eggers were very flighty and distrustful, largely because I got them as older poulots. But as time has gone by, they are curious, and they know who brings them treatos.

They see my older girls (the silkie and Australorp) that trust me, and they learn QUICKLY.
You're going to do great, and yes, those first eggs will be the most expensivest eggs ever, the poop is REAL, the loudness factor is legit, and they are destructive! But I love my girls, and am so appreciative of the lovely, delicious eggs they provide. Seeing their quirky personalities emerge is fun. Cheers!
