First, I recommend consideration of first-person POV, minor character, despite the fact that Robert Meredith and John Fitzgerald (in STRUCTURING YOUR NOVEL) recommend against it. For a novel, they're probably right. But for short stories, that POV makes several interesting effects possible. The very limitations of the minor character can become a strength for the story. In Ring Lardner's classic story "Haircut," for example, the barber who narrates the story is almost totally a spectator. He provides the reader with enough information to conclude that a murder has been committed, yet the unthinking barber never questions the official verdict of accidental death. This gratifies the reader with knowing more than the narrator does. Since the unperceptive barber typifies the attitudes of the town he lives in, I suppose one might argue that he's a major character. In any event, Lardner's use of POV adds an interesting complexity to the story.
Second, I'd like to recommend the objective POV for satirical short stories. This goes directly contrary to what is often said of fiction--that one should create interest by portraying intense emotion. In satire, part of the fun can be the absence of appropriate emotion in outrageous circumstances. The interesting complexity here is that the reader's normal response to outrageous events contrasts with the characters' apparent acceptance of those as part of the everyday world.
One word of warning, though: objective viewpoint is extremely hard to maintain. For an example, try Hemingway's "Hills Like White Elephants." The POV is almost totally objective, but near the end of the story the author (whether intentionally or otherwise) allows the male character to perceive that everyone in the station except the woman is acting reasonably. Is this an artistic lapse? I don't know. I do know that Hemingway got by with it, while we lesser lights could not.
In most cases we should follow the conventional wisdom in choosing POV. But the skilled writer will consider these variations to add spice to his writing.
