Well if you're quoting from a Nikon list of lenses, you missed the most obvious recent addition.
Sure, with the f4 or f2.8 you're shorter than 70-300. You can isolate subjects far better, focus better and quicker, shoot in lower light, take tele-converters if you wish. The VR was far better that the 70-300 of mine (when that worked). Rent one or borrow one and see. It's a completely different ballpark!
Sports - ideal focal length for some sports, especially with the ability to crop that larger MP bodies give you
Wildlife - no it's not ideal - you'll need longer, unless you shoot your wildlife in a zoo, birdlife close from a hide, or live in Galapagos or South Georgia
Wedding/Portraiture - a good solid performer, not so much isolation compared to an f2 lens at 135mm or 105mm, but good through all portrait local ranges
It's a solid and very usable focal range for a variety of uses. I'm happy with my 70-300 for what I use it for, but the 70-200 f2.8 is miles ahead for bokeh, IQ is stellar, and it doesn't hunt like the 70-300 at all.
