2 weeks in July: need your help deciding between Mongolia, Madagascar, Russia, Norway, or Armenia/Georgia.

I live in Canada. This July, I'll find myself in Istanbul with ~2 weeks free to travel. I've narrowed potential destinations down to Mongolia, Madagascar, Russia, Norway, or Armenia/Georgia, but am having trouble committing. Looking for any of your thoughts or experiences that could help tip me in one direction or the other.

I'm relatively well-traveled and most enjoy being in nature and spotting animals. I'm drawn to the hut-to-hut or village-to-village hiking in Norway and Armenia/Georgia, the opportunity to see some disappearing animals in Madagascar, the summer weather and landscapes of Mongolia, and the chance to visit a couple world-class cities and remote Siberia in one trip to Russia. Thank you.
