I have read elsewhere that people have created Adobe profiles to supplement the on-board, automatically applied profiles. But I never paid attention because the quality is difficult to evaluate without doing tedious testing.
The Occam's Razor answer is the Fujifilm parameters should suffice unless there is evidence that says the solution needs to be more complicated.
The 18/2 XF lens requires very large barrel distortion correction parameters. The lens does have issues at the extreme frame edges when highly structured content present. The first order barrel distortion corrections parameters are not sufficient. The result appears to be CA… but it's not. The ACR/LR Defringing and Clarity sliders often minimize these artifacts. Otherwise, the Fujifilm profile works well.
Occasionally there is residual transverse CA in 18/2 images that requires tweaking in LR. Even silly levels of pixel peeping does not reveal transverse CA for my copies of the 14/1.8, 23/1.4 or 35/14 XF lenses.
