This is not a Fuji problem - it's an issue of learning to use software to get the colors the photographer wants. The Fuji has the same drop-in digital sensor and therefore similar color response as a bunch of other well known and current MF cameras including some by Phase, Hassy, and Pentax.
If the OP were to ask the question again as "how do I learn to process my Fuji images when I'm used to working with C1" we might be able to advise better. There is no shame in wanting to learn to do something
This hugely underrates the difficulty of creating a natural, robust, beautiful profile for a camera.
It requires both art and science and in 11 years doing this, and working with many PHD Color scientists, industry “colorists” (color graders), photographers, retouchers and Digital Techs, I can count on one hand the number that I think really understand the process of crafting a proper color profile for a camera.
Hint: if someone thinks it’s as simple as pointing a camera at a target and throwing the result into (software x) to generate a profile, they are very sorely mistaken.
One reason to buy a modern Phase One or Leaf back is (because P1 makes both the hardware and software) the profile included in C1 is a real work of art.
To the OP: if you’re in the USA and would like to try an XF to see if fits your needs, please let me know; we would love to help you with your evaluation.
