If I were to have one bike and only one bike, I would want something more versatile than a road bike. I currently have two bikes, one is a rigid hybrid and the other is a cyclocross bike that I use more as a road bike. Both have cargo racks to carry my bag and the hybrid has mudguards for wet conditions and because I have to deal with sprinklers riding through the park at night.

The bikes you have chosen all come only in one size except that last one, but even then there are only two frame sizes. The hybrid I have comes in 5 different sizes and my cyclocross bike has more than 10. A lot of people are surprised to find that bicycle frames come in different sizes to accommodate differently sized riders. Even two people of the same height might find that they prefer different sizes. The frame size is usually a measure of the seat tube, and as the frame size changes, so do other dimensions of the frame, so in most situations, you can't just get a small frame and put in a longer seat post.

Bottom line is if the bike does not fit you, the ride will not be pleasant.

Low end bikes use cheap components that are sometimes difficult to work with or wear out quickly. Sometimes bearings don't turn smoothly and are instead notchy. And I don't know that I'd trust a bicycle built at a department store. They are generally put together as quickly as possible and the bike is not tuned to work well so gear shifts may not work well, brakes may not work well, wheels out of round, etc. Shimano makes parts for bicycles that range from $100 to $10000+, so Shimano parts doesn't necessarily make a good bicycle.

A quick look at the last bike shows a 42/52 crankset which is a very narrow gearing range. This is does not sound like something I'd want to ride in a hilly area. Compare to my triple 50/39/28 crankset and the compact double crankset with 50/34 which seems to be the norm amongst recreational riders currently. Triples are out of style now, but still a lot of avid supporters of triples.
