There is at least one Sorbus of very upright habit - think it may be
'Joseph Rock' but may be wrong on that - it is a yellow berried one.
Some of the birches are upright in growth as well.

I have seen this in my local garden centre; it's a fastigiate from of
'Joseph Rock', I believe it's called 'Autumn Spire'. It's an attractive
tree, with each leaf comprised of many leaflets, so giving the "small
leaves" look desired. It is still going to take 10 years or so to get to 15
foot in height, though the trees at the garden centre were about 7 feet tall
already.

Pot grown GC sorbus will take that long. If you buy the same trees,
slightly smaller, bare-root from a tree nursery (next winter, too late
now)they will grow *very* much faster, and with good planting and care
could reach 15 feet in half the time. Also, they will cost a great deal
less than potgrown from a GC.

Just as an example, I bought a pot-grown Joseph Rock which grew
slowly, though of course it also flowered and fruited. I grew seeds from
its fruit, and within 6 or 7 years the seedlings had outgrown their
parent.
