In reply to Graeme G:
For me, external controls that are accessible even with gloves on are most important. Especially exposure compensation dial, and protruding shutter button. Consider that if you take photos in the mountains and in the cold.
The Fuji 100 series is great, and reasonably controllable in gloves (especially if you add a third-party bigger screw-in shutter release button, I took some quick snapshots even with down mittens on ), although you would be limited by the 35mm fixed lens in the mountains. It's more of a specialised camera, but I like it a lot.
The zoom reach of the RX100 VI is very nice (24-200mm) for the mountains, although you do pay for it with smaller aperture than the predecessors, and the controls are for me just too small and fiddly for comfortable use with gloves (it's the smallest camera out of them all, though). Also it's so expensive for a compact.
If you never intend to switch lenses, and 24-75mm zoom is ok for you, consider the Pana LX 100 II as well, m4/3 chip and pretty nice controls. Otherwise, most m4/3 cameras with compact lenses would be still pretty smallish, and most offer enough external controls for use in the cold (plus the zooms would be mostly mechanical, as I don't really like push-button motorised zooming).
Nowadays, most of the cameras are so good I think you better find one that really suits you and your style with its controls, rather then pore over the technicalities.
