Have you checked into a greyhound rescue? I personally don't have experience, so my suggestion may not be great, especially if this is your first dog, but I do know they fit all of your qualifications, other than weather tolerance. They definitely need clothing in cool weather! Hopefully someone else with more experience can help.

Edit: I also like Greyhounds of America, because they require quite a bit of research on the breed and such before going through with an adoption. They seem really dedicated to making sure the dog they match you with will be a good fit for your situation and also making sure you know what you're getting into.
