There's definitely a certain style with VFDs that I'm a little surprised hasn't been adopted by people looking for a retro/cyberpunk aesthetic. I was looking into them when it seemed my decades old alarm clock might need a replacement, and they seem quite rare which I assume the economies aren't there in making something more complex and delicate. Interestingly there's a few clocks repurposing cooker displays, I'd guess a manufacturer had a large stockpile of displays for models they discontinued early and liquidated them.
