I was looking through some climbing Teas, Tea-Noisettes, and other random climbers that I thought would like your climate. Combining that with your preference for few to no thorns, color, repeat, and general health, and I think I came up with something that'd work for you.
'Mme E. Souffrain'

I have no experience with this rose, but genetically, it's very much 'Reve d'Or'. So for more pictures of its grandparent/parent for ideas about likely growth-habit, see pics below.

And that, too, may work well for you, but the "thornless or almost" note on 'Mme E. Souffrain' was what caught my attention.
It's other parent, 'Duarte de Oliveira', could also work, but be harder to find.

Tea-Noisettes are probably a good fit for your climate, especially where you plan to use them. They are pretty healthy in a hot and humid climate, and where you want to use the rose should get a good amount of air circulation, anyway.
