I'm riding a 19" gen 2 Sherpa and I'm shorter than you and it doesn't feel that long at all, still using a longish stem. My legs are relatively short though so the dropper post has to be short with this seat tube length but it's nice to have as big frame bag as it is.
The missing seat tube bottle cage mount doesn't matter with the frame bag, but a mount under the down tube would be handy for some trips. https://www.lfgss.com/conversations/339556/
Its Reynolds 853, but I don't know where it was made.
I've understood the gen 3 has some differences in the geometry, but otherwise the same. Basically steeper STA and more reach, same ETT. Few mm lower BB.
