Bike help please

I am a newbie, and getting overwhelmed with options.
I have been looking for a bike, my budget is $950 max.
I had the Ozark Trail G1 Explorer flat bar (in a medium to start,then went to a small) it was just not comfortable at all for me (neck,back,arm and hand pain). It just wasn't enjoyable. I ended up returning them.

They type of riding I'll be doing is majority paved bike paths, maybe very rarely a dirt/sandy path.
I made it about 6 miles on the OT before I had to walk it back to my car. I just couldn't go any further with the pain.

My husband just bought a Specilized and is trying to talk me into it, but his cost more than id like to spend.

I have looked at Specialized, Cannondale, and Trek. But looking at them all is like gibberish to me. I'm getting overwhelmed 🤣.

I found these 3 Trek bikes in my budget, and was curious if they'd work for just crusing bike paths and what the difference is between them?

If you dont think they are good options, I am absolutely open to all suggestions, advice and options/opinions.
I am very open to used also. I am in the NE Florida area if that helps any.

I also would like something with only 1 shifter (hopefully that is the right term i am sorry if it isn't).
Thank you all in advance.
