With your kit, landscapes are covered.
For wildlife, you'll get bison and elk easily with the 70-200. Other wildlife will be hit or miss.
I had a 300 f/4 with a 1.4x, and got croppable views of a Grizzly (Scarface), black bear and moose. I saw wolves, but would've need an 800 to get a meaningful capture.
And yes, you should expect that it will be beautiful, and amazing.
