Air carrier pilot reported a late approach clearance contributed to an initially unstabilized approach and bounced landing. Reporter stated the recent N90 TRACON change results in approach vectoring that creates a high pilot workload and increases the chance for errors.

Narrative

I was a PF and the CA was a PM. While we received a very late approach clearance and almost ended up above the glide slope after querying ATC multiple times; the approach was stable at 500 as required. There was a tailwind on the approach as well making the speed control more challenging. Neither myself nor any of the two PMs noticed any deviations outside of the stable approach criteria. As I initiated the landing flare; everything looked normal and within standard parameters. Right after touchdown; the aircraft bounced slightly followed up by a nose up pitch after which the Relief Pilot called for go-around. The CA decided to take over and fly the go around and the subsequent approach/landing himself which was uneventful.On the side note; the recent change in the NYC TRACON caused a lot of challenges coming into EWR. The approach vectoring/clearances usually leave the aircraft high and fast; making it a more challenging task to stabilize the approach. While this itself does not cause any unstable approaches as the pilots still have the option to go around; it unnecessarily introduces additional workload for pilots and increases the chances of errors occurring; and this was not the case prior to the most recent ATC change.
