I wouldn't really say that MTB are versatile. I've got a couple of MTB's, an Enduro long travel, and a specialized hard-tail 29". The Enduro is good for bike parks and some trails, whilst the hard-tail is good for some trails and cycle paths.
To make the hardtail versitile i have fitted thinner faster rolling tyres which are perfect.
If I had your requirements I would opt for a hybrid every time, as no doubt you'll be on the roads as well. No bike can cover all areas!
