Cornelia' from hortico.com they sell it as a Musk rose, it is my favorite rose bred by Pemberton, small blossoms in profusion, scented of musk and rose.
Blush Noisette'

Mermaid (hortico.com a climbing rose that I've espaliered on my back fence to keep it in line, spicy fragrant lemon yellow rose with beautiful red filiments.
Red and fragrant Hybrid Tea rosebushes, disease resistant in my no spray gardens:
Souvenir du Claudius DeNoyal
Crimson Glory
Papa Meilland , not floriferous but the cupped roses are huge goblets filled with perfume, when fed well.

In our latitude all the China, Old Garden Tea and Noisette rose are shade tolerant, for roses this means they still need 6 hours of full sun, or 4 hours of full sun and 4 hours of filtered sun
the most fragrant Tea I've ever smelled is 'Anna Olivier' it is very disease resistant even on the coast by the highway near Monteray.

alba class roses need fewer hours of sun: 4 to 5 will serve in this latitude, all Alba roses bloom for 3 to 4 weeks in one bloom season each year, but they are very pretty plants even when out of bloom.

I have grown all the roses listed above except for Reverend Seidel' in my no spray gardens in Oakland, and Richmond, Califonria.

Roses to avoid in no-spray gardens in or near San Francisco, Ca or wherever conditoins favor the spread of powdery mildew:
Georgetown Tea
Ducher'
both defoliated in my garden from p.m. and this greatly lessened bloom production.

Feed the soil first before you think of fertilzing.
I love Orchard Hardwares "Rose Soil" I used to have to mix c. 10 different items and micronutriets with alfalfa meal and bone meal etc.
but its all in the rose soil. I use 1/2 bag for each hole for a regular sized rosebush (4 to 5' tall) to a full bag for climbers, and large Tea rosebushes, be sure and mix native soil in with it, or you will get the bathtub effect.
50% to 60% rose soil depending on if you have the heavy California clay that I do.
a shovel full of well rotted manure, horse is very good, organic steer manure is also fine
25% to 33% of native soil, the soil from the hole you dug.
well rotted compost to bring it up to 100%

just f.y.i. I'd do a ph test before you begin, roses like slightly acid soil, do another test after you mix the soil blend and plant the first rosebush.
Good luck,
Luxrosa
