I had taken position after coming down from the tower working Ground Control. A priority handling had been coordinated with Aircraft X with an engine out. This had been coordinated at least 45 minutes prior to the aircraft's arrival. It was briefed from the relieved controller that this aircraft had requested 'wide vectors for an ILS.' At the same time Aircraft Z was inbound on the RNAV arrival along with Aircraft Y call sign unknown. In my judgement as well as the relieved Controller both of these aircraft would have arrived easily before Aircraft X came in on the ILS. I cleared Aircraft Y for the Visual Approach to the right parallel runway and decided to change the Aircraft Y to the left after they requested the ILS. Aircraft X changed his mind for the Visual Approach which I approved. I asked Aircraft X if they could visually follow the Aircraft Y and they said they would not because of wake turbulence. Since I did not issue a 30 degree intercept we coordinated with the tower to issue a go-around to Aircraft Y. We decided not to send the Aircraft Y around because he was established on the ILS even though I had not issued a 30 degree intercept for Aircraft X. In my opinion wake turbulence to a priority handling aircraft was more of a factor than a parallel runway approach.Due to the busy nature of this session I think splitting the radar position may have been warranted. The relieved Controller had been on position for over 1 hour and 45 minutes. Aircraft X changing his mind mid sequence also caused a lot of problems. I was wary of issuing delay vectors to an aircraft that was a priority handling.
GSO TRACON Controller reported improperly turning an aircraft onto final with another aircraft on approach to the parallel runway.
