You could go either way, depending on your visual preference. I am 5' 8", with similar proportions. I have a Soma Sutro stem on a couple bikes. It has about 40 mm more rise than most standard height stems, so it doesn't look horrible. https://www.somafab.com/archives/pro...tro-quill-stem Nitto Technomic stems have about 80 mm of extra height, so they won't work on frames with a smaller head tube if you don't need all that.

I have also used a shorter stem on a bigger frame, but I didn't like how it looked. Going from 100 to 80 mm isn't bad, but from 100 to 60 mm is too much, IMO.
