RF 15-35 or 24-70 as next (have EF24-105 f4)

I shoot with EF 16-35mm II USM and EF 135mm f/2L USM on R6 for most of the time and I'm very satisfied with this combination. Some people may feel more secure having the whole focal length range covered but I find this unnecessary. The extra range covered by 24-70 can easily be compensated by zooming with your feet, or some slight cropping.

If you shoot videos, also beware of the slight 1.07x crop of videos on R6. If you enable movie digital IS, the image would be further cropped. 15mm would be perfect with this slight cropping. It reduces extreme distortion, and is just wide enough for most purposes.

I would definitely go with the RF 15-35.

If you shoot indoors there are many cases where you can not back up enough to get the subject of the shot in the frame. You can crop for more range but there is nothing you can do in these cases to get more in the frame of a 24-105mmf4 lens. The 15-35mm has great f2.8 wide open light gathering for indoor shooting. A small compact bounce flash can help too.

For travel, the wide coverage of 15mm is great for inside churches and for outdoor travel you can grab the whole landscape. I have rf 15-30, 24-70, 24-105mm, and 24-240mm. The 24-105 is used primarily for video outdoors for constant f4 zooming. For nearly all travel the 24-240mm is very handy and get used a lot. I only have the EOS R now but a R5 is on the way. I use a EF 70-200f2.8L II for sports action shooting outdoors which I owned for DSLRs. It works well adapted to the RF mount so I did not get the RF mount version and the RF lenses I bought are my core lenses for the EOS R use while I have other EF mount lenses for special cases. I really like the sharp focus o f EOS R but I very used to using the truly great EOS 5DMkIV DSLR from years of use. The EOS R now makes more keepers for me where sharp focus is key except for fast action shots where I use DSLRs.

While I don't disagree on the potential usefulness of an UWA, they are specialty lenses.  I put them in the same category as macro lenses and super telephotos.    It should be obvious if you need one.    If you are often at 24mm and can't back up (or get close enough for the perspective you want) then you need a UWA.  If not, it's probably going to spend a lot of time on the shelf.
