Sure, a silver birch could grow to 80' if the conditions are favourable (it might not), but how long would that take? 20-50 years? My gardening is more on a 5-10 year timescale: I'm happy to remove trees/shrubs if they outgrow the garden.
Pyrus calleryana chanticleer, holds it's leaves for a long time compared to almost any other deciduous trees and grows a wonderful shape. A couple of these 3m apart would work well.

But why plant a tree totally unsuitable to a suburban garden when there are loads more options that are better behaved?
Fair point. I saw it as a trade-off between air-cleaning properties vs longevity in the garden. For me, I think the former is more important.
But if there's a nice-looking tree that cleans the air and will be good for 20+ years, then of course that would be preferable.

Irish juniper and J. scopularum 'Skyrocket' grow in a similar way to Italian cypress, but more likely to survive if you live anywhere chilly.
I have had both, nice tidy trees for a focal point or strategic planting.
