It's 50 degrees F outside and I don't think I want to swim

 

Aside from correcting the lens distortion, the above image is the result of in-camera-shot using the Fujifilm X100F.  No other post-processing.  Really. 

I found this free app called Fuji X Weekly Recipe that gives one access to over 100 Film Simulation Recipes for Fujifilm X cameras.  I dig it that these JPEG settings allow one to get various looks straight out of camera, many based on film stocks, such as Kodachrome, Portra, Tri-X, Superia, Vista, and many more.  The caveat is that you need to have a compatible Fujifilm X camera such as X100V, XT, X-pro and so on.  I believe the app has been around for a year now.  

The above image was captured with the Fujifilm X100F using the following recipe for cross process:  Film Simulation - Classic Chrome; Dynamic Range DR400; Highlight +4,;Shadow -1; Color +3; Noise Reduction -4; Sharpening +1;  Chrome Effect Off; WB 7700k, -8 Red & -3 Blue; Exposure compensation -1/3 to -2/3.

I think the real key to get that color tone is to get the White Balance right.  A bit cumbersome but once you plug in the settings it can be saved as a custom preset in the camera.  

Although I think the greenish tone of cross processing is cool, it's a bit over the top.  The image probably should look like the one below.  I adjusted the White Balance and left a bit of the cross processing tone.  Let me know which one you prefer.

Finally, I exported the jpeg image to my iPhone Lightroom and rendered it using my own preset that could make everything look crazy:
