IMO, there's no stretching involved here. I tour and commute on hybrid and/or CX bike all the time. What you're describing can be done on most any bike. I too would forego any suspension systems, especially at lower price points. Not only for the added weight, but also for added maintenance. The winter hybrid I bought a couple of years ago came with a completely useless suspension seat post. I have no idea why anyone would want that. The only advantage is, it's easy to replace.

There are many variables that play a role in ride comfort, not just frame material. Fork geometry, saddle, fit, tyres, handlebars to name a few. Since the "feel" of the ride seems important to you, it might be a good idea to concentrate on bikes you can test ride before deciding.
