Welcome to BF.
The effective top tube length on this model corresponds with their stated size. I'm 6'1" and ride road bikes with 58cm tt and 12.5 stem. For a gravel rider, a shorter stem at about 10cm is recommended, so for me the 60cm size would be good, especially with the taller head tube to reduce the saddle to bar height. Lots of riders believe a longer wheelbase makes a gravel bike more stable.
Not sure about the height or arm length of the OP,
edit: checking the Salsa site, the longest stem offered (in the online specs) is 9cm.
