Ideally with one engine inoperative you should actively manage your fuel balance state and don’t wait for the advisory or ECAM to trigger the fuel balance procedure and this should avoid unwanted distractions on approach. If circumstances haven’t allowed you to do that then providing you have sufficient fuel in the feeding tank accept the imbalance and land.
For Airbus there is no limitation on landing or go arounds whilst still cross feeding with one engine inoperative. Certification requirements don’t allow takeoff with both engines feeding from a common tank to avoid multiple engine failures due to contamination or a fuel delivery type failure. I would avoid a cross feeding for approach and go around with both engines operating for the same reason but not in the OEI case.
