You may be over thinking this, as most bikes will be a compromise in some way. Go buy a used KLR and put some miles on it. It is a simple and forgiving ride and it will help you discover how you want to ride. You can almost always sell a good used one for what you paid.
I put 20k miles on a 2007 before moving on to a 990 and there are times when I still miss that bike.
