The lenses I use in the mountains are the 12-40 2.8 an awesome lens but not the smallest MFT lens.
I also have the 9-18mm which is pretty compact and gives a 18-36 equivalent
I’ve also used a 15mm Panasonic lens which gives the same field of view as a iPhone 😏optically very very good and a compact and versatile lens.
I've started using the Olympus a little bit more in the mountains (I also use Nikon full frame) it can capture great pictures, compared to the Nikon full frame it will struggle a little with dynamic range when pushed but it will beat any compact camera.
The mega pixel count doesn’t really matter unless you routinely dramatically crop pictures and even then you would be surprised what you can do.
The weather proofing and image stabilisation are top notch and I routinely get the camera out in shit weather.
As for simplicity a few minutes with the menu and you can set it up in point and shoot mode.

optically I personally think MFT are among the best lenses I’ve used and there are enough out there to cover your needs. Some of the ultra compact zooms are optically compromised and a little soft so I would avoid those and take the small penalty in size.
