How about getting her a subscription to a streaming service that specializes in documentaries like CuriosityStream or DocPlay? This way she can watch as many documentaries as she likes. Or if you want to get her something tangible, you can buy her a DVD collection of her favorite documentaries or a book about influential documentary filmmakers, such as Ken Burns or Errol Morris. Another idea could be to organize a private screening of a documentary that your wife has always wanted to watch, with her closest friends or family.
Or you can get her a star map with the date when she was born.
