I've had a 2013 Suzuki 650 vstrom and they are an excellent bike for solo riding. Price is pretty attractive and they have proven to be dependable. My wife and I road our 650 for a 2 week road trip and in spite of being overloaded it handled the trip without complaint.
Another one to check out, a bit smaller than your 700 gs, is the Honda CB 500X, 2019 & up. I took one for a test drive and was really impressed with its road manners. It only has 50 hp but is really light, so for its size has a fair amount of get up and go. I wouldn't consider this one an interstate bike, but for just about anything else it would work well.
Lots of choices out there and I have nothing against the 700-800 gs, and have even toyed with the idea of getting one
