Thanks for sharing this great piece and advice. I too love my Fujifilm camera, the X-Pro2. And I only shoot JPEG. I agree wholeheartedly, why waste all the storage space. The reality is most photos are used online, and JPEG's work best.
After a number of years shooting only with my iPhone, I used Snapseed for editing. It's second nature to me, and very intuitive. The controls are so similar to what I did in the darkroom for so many years. So I continue to edit my Fuji images in Snapped as well, and could not be happier with the results.
