I am not sure if the post of @herbert-50 was already mentioned or not? But with his styles, I got pretty good results in replicating fuji-jpegs. What I like about his styles, he uses
- filmic RGB as the base for the style
- a tone curve for contrast
- a color lookup table to match the color with the simulation
so you can also, for example, use only the ClassicChrome colors in your edits. What I quite like.
He also has a lengthy blog post how he created the styles, but only in german.
I hope this helps you
