I'm going on a 9 mile hike this Friday to Mount Humphreys in Arizona. It is the highest peak in Arizona at 12,400 feet. Once on top the view is breathtaking. Here are my choices for Camera's, I only want to take one. I'll have a daypack with water so I don't want a lot of weight however I want clean sharp shots from the top. ...
Any of the cameras you listed will make "clean, sharp shots from the top." They'd all do MUCH better at that if you brought along a sturdy tripod, as any landscape photographer could tell you. Between 28, 35, and 50 mm FoV at a mountain peak viewpoint is mostly a toss up.
Let's think about your expectations and what you shouldn't expect. None of those cameras hand-held is going to rival a technical camera's results, no matter what you do. Atmospheric conditions will have a bigger influence on what you capture than which lens or FoV. If this is your first time working large scale, distance landscape shots from high altitude, expect some thing of a learning curve.
So ... Personally, I'd grab the X or the Q (toss up), a couple of storage cards and at least a spare battery, and go have a good time. Concentrate on taking photos of the event, rather than specializing on the big vista. Photos of the meet up point, the troupe getting ready to storm the trail, the fun you have along the way, having lunch, rest stops, etc. Tell the story of the hike in other words. When you get to the top and see the big vista, take several photos, trying different points of view, and capture a sequence or two for stitching into a panorama ... Don't sweat it too much, just work methodically and get the best you can. Record the trip down the mountain too, and get everyone together at the end for a group shot at least.
To get a good story and a decent shot or two of the view ... that will make a memorable set for the future. Enjoy the event AND the photography, the latter by not trying to put too many expectations into it, and by not lugging more gear around than you need to enjoy the day.
For me, I'd grab the X, a spare battery, and have a great day. I'd carry the M and a couple of lenses the SECOND time I did the trip as then I'd know much more what to expect and how to tailor my equipment carry to reach a photographic goal.
