Yes, we have them in DR, one bath, and new Den. As others have said, they are great. You should know that you can get these from Hunter Douglass in a cordless version, you just raise or lower (top or bottom) by grasping the tabs at the top or bottom. Of course these are more expensive. We got ours online for a pretty good price. For the den that we just finished, we went with top-down/bottom-up cellular from Next Day Blinds. These have cords, which do not bother us in this room. None of ours are room-darkening as we wanted to let in some light; all provide privacy. They won't interfere with window hardware as long as you have enough depth in the window to provide clearance for the shades. Talk to your dealer, or have them measure, if you have doubts.

Oh, my windows aren't as high as yours so that makes a big difference. Cordless is great but not if it means you'll fall out the window while straining to reach the top. My upstairs room has the BU only feature since the window is higher in that room & the top is unreachable and also I couldn't imagine a situation when I would need the top down. The downstairs room needed the TD/BU, for privacy and light control options, but I can reach the top of the window so it isn't a problem. And if I can reach the top then I'm sure all my guests can also. Wasn't there a recent post about power controlled window coverings for high, hard to reach spaces? It was a beautiful room with sky high windows and a lovely fireplace. Realistically, how often will you have to adjust the top? Frequent changes might make the cost of power control worthwhile. Infrequent might make using a pole, and finding a place to store it, tolerable. Or maybe someone else will have a better solution for you.

I purchased a fabric Roman shade that was top down/bottom up in the master closet in my previous home. It was from Smith and Noble. I don't have any photos, but it was really nice.

Have you looked at Hunter Douglas honeycomb shades? I just checked the price list. Your length is too long to do top-down/bottom-up cordless at that width. But, you can do top-down/bottom-up with UltraGlide, which is a tension wand system. I also wouldn't recommend cordless on that height because you would have a very hard time reaching the top of the shade to lower it from the top. The other option would be to do two separate shades on each side of the door (one on the stationary side and one on the side that slides). That way, if you want to go in and out, you don't have to raise the shade completely and have the entire glass exposed. I see that you don't like the vertical option, but honeycomb shades do come in verticals. Usually at doors that size, we would do the Duette with VertiGlide.
