If Fuji lenses only, I would go with the original 4 : 14/2.8, 18/2.0, 35/1.4, 60/2.4. #2 and #4 in this list are very underrated. They do bring what we are looking for in vintage lenses
If we allow Voigtlander in the list, then my list would be : 14/2.8, Voigt 23/1.2, 60/2.4 and the wonderful 70-300
I am getting excellent results with Mamiya 67 lenses and Pentacon Six lenses on a GFX 50S and a GFX 100, via Hartblei adapters, including tilt and shift adapters. See here: https://pentaconsix.com/digital2022.htm and here: https://pentaconsix.com/hartbleigfx.htm
Other links from those pages give more information and examples of results.
