if you use a MAC or MacBook Pro Imovie is excellent for good slideshow and music all done in a very quick time with good transitions and editing options.

I would rent a longer lens as the bear shots and wolves will take a longer lens.

I personally use the Nikon 28-300 lens as a walk around lens and have done it for years on my D850 and it has been excellent. It hits most every need I have while being light weight and short. I think you would enjoy using it and most likely will find that you will hesitate to carry many other lenses unless a specific need. Good luck.
