New Diverge bikes, sizing help?

Buying my first new bike ever, after coming from a random bike I got when I was much younger that is much too small for me. I'm thinking of the new Diverge 4 Sport Alloy after getting a ton of recommendations from various friends and family, so curious about folks experience with sizing.

I'm 6'3" but I have a much longer torso than legs -- my inseam is around 33" / shin length around 17", and I think I'm between a 58 and a 61. Anyone with similar builds have advice on what fit them best?
