how many bike shops are close to you and what brands do they sell? Are the people that run the shop older and possibly getting out of it soon? I had a bike shop, and when the owner died it closed, so now I don't have one

It's not a major concern because with bike forum and youtube you can do all your work yourself (don't forget the tools), but having a good shop nearby to me is a positive

are you committed to flat bars or are drop bars an option for you?

any of those bikes you listed will work, The best bike is the one you want to ride. Your major topics to think about now should be saddle, bars, and pedals. If these are right, then the bike is right

you came to the right place, but don't be thin skinned

post as many details of your situation as you can. wants, needs, how much to spend, riding goals, height, weight, past cycling experience

there are tons of really knowledgeable posters here who can help you
