How best to attack a seized and rounded top cap on a BMX? Loosening the stem bolts and spinning the bars and stem didn’t budge it.

If it's just the top cap that's seized I'd try poking a some something in the bottom of the fork crown and hitting with a hammer.
Dremel cutting disc to cut a flat into it, lots of penetrating lube, and torque it out with a flat piece of metal on a handle.
An Easy out should work.
You should also prep it with pentrating fluid to get it moving along.
Other option is to drill and tap a couple of bolts to attach a bar of some sort and lever it out.
