Aside from "Fourteen Experiments...", none of your selections really left me cold, but off the top of my head, I would have to mention:
Hotel Astarte: Really gorgeous language and wonderful imagery, plus a moving story.
Moon Viewing at Shijo Bridge: The first Giant, and again, just a gorgeous story driven by a really interesting main character.
The Osteomancer's Son: Modern/Dark fantasy. Great piece about relationships, plus really cool magic.
