my opinions....
that Yamaha 650 bike is gonna be too small for the both of you. if ya'll take that thing on the highway together it's gonna be struggling. the Suzuki M109 is too much bike for a beginner bike. it's really powerful and not as necessary since you just want to go on short weekend rides. for your size and riding tastes i wouldn't suggest anything bigger than the C90 you mentioned. i would use that size as the maximum you want to go with, as far as engine goes since it's over 1400cc.
for your price range and for a bike that size, the Honda VTX1300 is a little cheaper as just as much reliable if not more so. very similar is the Yamaha V Star 1300. besides the 650 you mentioned, all these bikes are fuel injected which is gonna be lower maintenance for you in the long run. if you don't want to have to perform any maintenance, and you're considering a used bike, i wouldn't suggest anything over 5K miles on it or more than 2-3 years old.
a great place to get some ideas is to search your local craigslist or cycletrader.com. i think either a Suzuki, Honda, or Yamaha is gonna give you the most reliable bike for the size and price you want.
