Human Factors
Night VFR RNAV Y XXR approach. Approaching FAF ZZZ tower advised us of Cessna  traffic on downwind turning base for short parallel runway XXL. Traffic in sight. As we passed our FAF; fully configured and stable we saw the Cessna pointing right at us on base and both remarked 'I hope they don't overshoot'. At approximately 800 feet AGL the Cessna was still pointing at us and I could see they were clearly going to overshoot slightly above us as they turned to final. I felt it was way too close and pushed over slightly as I estimated them to be no more than 100-200 feet above us as they crossed right over us and slightly behind. As our approach was now unstable in my estimation I executed an uneventful go-around. We advised tower of the close pass. We returned for a second; uneventful approach and landing to XXR. I called tower controller after landing and he said he would contact the Cessna pilot and talk to him about the incident. Cessna not keeping us in sight and possibly lining up on incorrect runway. Light VFR traffic maintaining better situational awareness with a large air carrier with approximately XXX people on board and all landing lights; fully configured on final approach.
Air carrier Captain reported an NMAC during approach with an aircraft on approach on the parallel runway.
