I reckon you're right about the Z (or R) being more suited to the terrain/roads. As for fuelling, yes the Z is better in this respect, but it runs lean and benefits can still be had from improved fuelling via fitting a Kev mod/Power Commander.

Yes, but probably no better than X/R with a tall screen. The XTZ does have some buffeting issues, but very much depending on your height, helmet choice, riding position etc. This of course can be improved with tall screens, short screens, diffusers and a bit of fiddling/ingenuity.

Only marginally, and I don't think you'd really notice too much, and that can be easily/cheaply changed with different size front (or rear) sprockets.

Don't get me wrong I love the Tenere; it is a great bike, but if you've got a perfectly good XTX (which you know where you are with) in the shed, and you're not going to a massive amount off road, then you've got some thinking to do! But - if your heart desires an XTZ, then get one; don't bother trying to justify it to yourself. I bought one without having even seen one in the flesh, never mind a test ride or anything so fancy. I know I made the right choice because I've still got it over four years later!
