Got a TCAS RA just prior to glide slope intercept on ILS. [A] single engine small aircraft was crossing above at 500 feet over us. ATC pointed out the traffic. Clearance was to maintain 3;000 feet until established and cleared for [the] ILS Approach. We could have started our descent before capturing the glide slope before the final approach fix.
Air Carrier First Officer reported they observed an aircraft pass 500 feet overhead and received a TCAS/RA.
