I'd definitely get something with a windshield, hand guards, heated grips and an alternator big enough to use heated clothing, and pretty good gas mileage with cheap consumables. I got a CB500X for most of the same reasons, but we don't get an actual winter here in Northwest Arkansas. Madstad makes good aftermarket windshields.
FJR1300 isn't a bad choice at all.
