Great list! I've found Desdemona does really well in a vase. It lasts for days. While the blooms are smaller it goes well with other roses in a mixed bouquet.
Update on the US DA website: The Lady Emma Hamilton is expected back in stock in 2023; Heathcliff, L D Braithwaite, Shropshire Lad, Evelyn, The Dark Lady, Falstaff, Sweet Juliet, & Pat Austin have all been discontinued and no longer show the “Expected back in stock 2023” note on their pages.
Here in the USA zone 6 I have had very good luck with first-year Tess of the d'Urbervilles. She lasts for a week or more! I am thrilled with her. Wonderful scent as well.
My Tess has been very vigorous and blooming aggressively in a pot no less. Fragrance is not the strongest, but still very good. Been one of my better DAs so far and I have a good many. Thorns are brutal on my Tess though.
