Since Fuji film simulations recipes are mostly, well, simulating films I've been getting quite a lot of compliments from customers saying the the pictures look "too artistic","dull" or "feels a bit washed color".
When you go looking, remember to take in account which sensor the recipe is designed to work with, you mention using a X-T4, so your camera should be okay to use a very large number of the ones offered.
My experience with my X-S10 and X100v suggests that using the standard Provia film sim, set WB to daylight and get your exposure right (use the histogram) will give you a perfect jpeg SOOC suitable for skin tones as well as water falls.
Old thread, but you could also try this site, oyvindwashere for some great recipes. I use one of these as my standard simulation. I stay away from the Fuji-X Weekly recipes, they play around with the white balance too much to make them usable, unless overly red/golden images float your boat.
