Landscape Lens Suggestion

I’m looking for some advice on a lens to rent for vacation. I will be taking the 70-200 2.8 and the R6Mii. I’m looking for something to shoot landscapes like whitewater rivers and waterfalls with. I’m looking at the following lenses below. Anyone have any advice or suggestions? I really liked the Sigma 14-24 but not being able to use a screw on ND filter made that one come off my list.

Canon 16-35mm f/4L IS

Canon RF 14-35mm f/4

Canon RF 24-105mm f/4

Since you were considering the 14-24, I'm guessing you like the UWA (ultra wide angle) perspective and can live with the distortions they (usually) bring so I would go for the 14-35. IMO, IS isn't as important in wide angles and for long exposures (hinted at with the ND filter comment) I'd again guess that you'll be using a tripod anyway.

Whatever you take, enjoy the trip!

One potential issue with wider lenses is that that thing that looks really big and dominates our view can maybe end up as something quite small in the frame and then there's perspective distortion to consider.

I'm a normal-ish view prime guy myself but of those zooms I'd be hovering around 35mm most of the time and maybe looking to go longer if possible. Wider you can sometimes do with stitching although I realise that not all subjects and scenes are easily stitchable.
