Concrete caulk vs expanding polyurethane crack sealant
You are really brave to finish a basement with a known moisture issue.  I for one wouldn't spend a penny on finishing my basement until I have seen it go through a wet season without failing.  Not telling you to stop but would warn to slow down.  Get your framing/electric/plumbing/whatever done and let it go through at least 4-5 months before finishing touches.

As for cracks, if it has leaked before then I would suggest that you always go with an epoxy.  There are too many on the market for me to give a recommendation.  I have used at least 10 and was happy with 8 of them.  Concrete caulk is not your answer to seal a leaking crack but can be used on the outside of the house to keep issues at bay.  Also make sure you read the instruction on the epoxy.  You are probably going to have to chisel out the crack to make it larger so the epoxy can fill it.
