Not all AF-S lenses are equal. The big guns, for example, focus massively faster than all of the consumer lenses. It depends on the speed and construction of the AF-S motor.
The 70-300 has a pretty slow AF-S motor, all things considered. If you use, for instance, even a moderately expensive lens - like either version of the 300mm f/4 lenses, or the 80-400mm AF-S, or the 200-500mm, you'll see a really significant increase in focus speed.
Very true that not all AF-S lenses are equal in terms of focus speed, but I have to say this is the first time I've ever seen written that the 70-300VR focus speed is "quite poor". Obviously you're entitled to that opinion, but I'm not sure how much general agreement you'd find. Relative to the tastest focus lenses costing much more, I have no doubt it's slower, but "poor"? Curious how I was able to get so many hummer shots with poor focus speed on various bodies.
To the OP if you want a lightweight zoom, I'd consider the Nikon 70-300VR or the Tamron equivalent. IQ and focus speed won't be equal to the 300mm PF, but definitely adequate or maybe even a little more than adequate. I would stop down either lens a little on the long end.
