everyone has been so helpful, i wanted to provide an update.
i did get my current bike's shifting checked out and it was a problem with the actual shifters. seems to be a little better.
here are some options i've found:
http://archive.fujibikes.com/2016/Fuji/sportif-21- size 49, $500---no upgrades, seems double the bike blue book value.
https://archive.fujibikes.com/2014/Fuji/finest-15-t2 size 47
https://www.amazon.com/Jamis-Ventura-Sport-Shimano-Monterey/dp/B07HCPQ74N/ size 48
i would need new wheels for any of these as expected but i think they'd get me started, at least.
