Not really. I wax afterwards. I have also used carb cleaner on very bad lenses. after I have wet sanded them with 220, 400, and 600. Then used the carb cleaner. Have brought back many really badly damaged lenses. But, Remember, no more than two quick swipes, or the lenses will start to melt. I can't take credit for the method because it was shown to me by a Factory Car Technician.

Works on CD's and for cleaning jewelry too.

Some of those lights aren't going to get touched by polishing compound, they need to be sanded first.

Like any other "Damage" it depends on the extent of the damage, it can be anywhere on the scale, and the extent you have to go to depends on this. If you can see through the lens with not much difficulty, and just a slight have, its minimal. Crest would likely work. If you cant see inside the light very well, more work may be requires. If you can feel the rough surface and you cant see inside at all, it borderline, and will take a lot or won't be able to be repaired.

SOme headlamps are cheap to replace, and may not be worth taking the time, but some can run 400 to 500 dollars a piece, and are worth restoring.

No one can really tell you what a reasonable or expected cost can be, because no two cases are alike, and the haze damage can be from a slight have to actual pits and flakes out of the headlamp material, which can be beyond saving. Keep your headlamps waxed, and park where the direct sun doesn't hit them during the day.
I use CarPro CQuartz. Designed mostly for paint but can be used on almost any surface found on cars (glass, plastic, rubber, etc).

It is easy to apply and lasts years. It's only been a year since I applied it on my car including the headlights and so far so good. Absolutely no haze and is water repellent.

If and when you have to restore the headlights the process of sanding down the headlights will remove the protective coating so no additional steps needed.

CQuartz works so good on my paint after I was the car I simply use a cheap battery powered leaf blower to make the water "slide" off the paint. No needless touching of the paint to wipe off water.
