I think linking that "doomer jazz" playlist would be the best bet, to give others some kind of idea of the sound you are looking for.
This is a total stab in the dark, but for me when I want that "coffee and cigarette in a New York apartment staring out the window at the rain in the early morning" vibe I usually go for Miles Davis' Nefertiti album. Especially the title track might fit your vibe? Or at least my idea of your vibe? I know this is 60s and not 40s but I assume we're not necessarily looking for something of the period?
