Human Factors
We were flying ZZZ1 to ZZZ; a XA00 report in ZZZ1. It was the First Officer's (FO) initial trip back from a 10-month furlough. We were on the ZZZZZ RNAV arrival from the northeast. I was the PF. ZZZ was landing north. ZZZ airport had an overcast layer obscuring the airport. At the appropriate time; I briefed the ILS XXR approach. We set up the FMS and tuned/identified the NAV radios for XXR; the normal approach for this arrival. When we checked in with ZZZ Approach; we were advised to expect the ILS XXL. I briefed the approach and we tuned/identified the NAV radios. We were being vectored to intercept the localizer. It looked like we overshot the localizer on the NAV display; so I turned to intercept. ATC advised us; 'It looks like you are lining up for the wrong runway;' and turned us off of the approach. There were no conflicts with any other aircraft. They then told us to expect the ILS XXR. We flew that approach successfully to a landing. While we were setting up for the XXR approach; we discovered we never set up the FMS for the ILS to XXL. [I believe the cause was] early sign-in. Overcast skies obscuring airport. [It was also the] FO's first trip after furlough. [I suggest] verification that both the NAV radios are tuned and identified and the FMS is set for the proper runway/approach.
Planned and briefed approach for ILS Runway XXR and was given ILS Runway XXL. The CA (Captain) set up and briefed new approach. I verified the frequencies and inbound course but neither of us set the new approach into the FMS. Was getting vectors to the ILS XXL [and] we had the correct ID for the ILS. When the CA looked at the ND and saw himself flying through the course for what was ILS XXR; the wrong approach; he corrected the heading to go back to intercept the course on the ND. The Controller said you are turning to line up for wrong approach and told us to go around.I have not flown since [last year]. I also do not have much experience in the aircraft. Was first flight since furlough. [I plan on] getting more flying in and becoming more comfortable in the aircraft; getting back into the rhythm of the flights.
