Also the longer the focal length of the lens the less CA seems to be an issue.

So faster and shorter focal length = more likely to show CA and more pressure on the lens designers to handle it.

I don't see very little CA on my Nikon 14-24mm at F2.8, I see very little with a cheap Pentax 67 165mm F2.8 wide open. So it can be done.

Generally speaking, a lens with ED elements is likely to have less CA.

CA is one thing usually tested for in lens reviews.

One of the best lens review sites I have seen is Photozone.de
