The heads up display isn’t something you see in front of you like most planes. The helmets are the heads up display, like augmented reality.
There are cameras all over the plane to help you see through the aircraft (see ground targets through the floor, nearby aircraft through your wing). Think of the resolution and bitrate needed to make it useful!
Just like how an apache gunner can simply look at a target to aim the gun at them you can do the same thing. And if you can’t hit it it’s still marked for every allied plane in the airspace to see. If you are out of missiles but you are tracking an enemy plane miles ahead, you can send the data to an F-15 miles behind you and let their missiles lock and fire from farther than they can engage alone.
With that in mind the radar is awesome letting it see threats from greater distances than the opposition, with the stealth capabilities good enough to keep them from easily doing the same.
I’m sure there are other surprises too, but the military obviously wants to keep those a secret
