Idk much about seeds to be honest I failed hard try to get a nice perfectly grassy backyard what I can tell you though is that to have your grass look Piff all your prep work needs to be done in late fall
With that said I will be hiring a landscaper
I'm cheap. I dont like to hire folks for shyt I can do myself. and by myself, I'm talking about cutting the grass, shoveling snow, and cleaning the house. it's four of us living here, so I got kids who can help with the chores, and as a man, I can do the grass mowing/snow shoveling. when it comes to gardening, then my wife gotta handle that, cuz that's not my area.
at our old house we had strawberries growing, cabbage, tomatoes, peppers and yellow roses. plus an apple tree in the backyard (which I hated cuz it attracted so many bees with the fallen fruit)
so she will have to get on it this spring if she wants to get something like that poppin.
