I like roses with scent. I'm leaning toward either a blood red, or a yellow with orange-red tips (sunset colors). I'm planning on putting it against a 3' open picket fence, not far from the tomatoes, but could also be convinced into something that didn't need a support, out in the middle of a bed. I have limited places with that level of sunshine (AFAIK it would need approximately full sun) that aren't grass, you see. No educated opinion on long stemmed, clustered, etc. Not really high maintenance either.
