I don't do much soldering (obviously) but which is better and is less
prone to cracking in the future? The newer Lead-free rosin core or the
63/37 tin/lead rosin core? A store in my town only stocks these two.
This for a small circuit board repair project.

If you have the choice use tin-lead every day !

Also, What can I use to cleanup the dried-up rosin residue on the PCB?

Do you need to ?

Most of the alcohols work fine for this. Isopropyl alcohol ( aka isopropanol )
is probably best and easy to obtain.
