Find the Best Film Recipe, then Quit Adobe? | Fujifilm JPEGs Vs OM3, Nikon Zf

The biggest problem with the most popular film recipe? It’s only available on Fuji. I found a way to copy Classic Chrome on the OM3, even Nikon now has their own JPEG recipes.  Can I create a look that works for all of my cameras using free software only? But the odds are against me - this is attempt number three. Can I finally quit Adobe?
