A David Austin fan here too, you can use the website to narrow down to roses that will do best in the situation you want, and you can add health, fragrance, fewer thorns etc. If you sign up for emails you will probably get occasional offers, for a percentage off
When I moved in there was a rose in the wrong place so moved it against the garage wall, it thrived, climbed maybe 4 meters, only once a year but such a lovely scent. But murderous thorns, event after we dug a pond a d the area changed, it didn't do so well and had to get rid of it. But so hard to get rid of those murderous thorned long dead branches, they were still pricking me years later when I came across a dead twig
If you do go for a thorny one make sure you get some thick gloves and plant it where no one one will have to run the gauntlet
DA have some lovely climbers which are not so thorny and smell beautiful and flower repeatedly
