P: Workflow changes to the new Denoise tool has made changes to Fuji x-trans rendering

I see that you are using LrC to convert the RAF to a DNG. In your case via the Denoise tool. A couple of points (that may be out of date)

• The new Denoise does not create a DNG by default. That is, unless you use Enhance (Enhance will create a DNG)
• If you either use that method or use the Convert to DNG method, you are in effect using ACR (built into LrC) that has or had the underlying issue with RAF (Worms, overzealous sharpening) 
• Many Fuji X owners who absolutely hate Adobe's treatment of RAF use third-party RAF to DNG converters. Specifically Irident X-Transformer. I would recommend that you try that out (a trial download is available)
• Not all Fuji X owners find that ACR creates those worms any longer, and accept the LrC/ACR treatment. Although it is often recommended that you undo the lousy Adobe default in adding sharpening at import. (The preset /Classic/General/Zeroed helps)

The functionality that was present before is still there. Instead of an [Enhance] button, you now have a series of Checkboxes in the Detail section for Denoise/Raw Details.
