When it comes to processing, is there anything you would recommend?
There's lots. Adobe offer a subscription model for their software these days, which includes lightroom (image development - like a digital darkroom) and Photoshop (for making bigger changes to pictures and a huge amount besides) - but many of us don't want to be tied into their subscription.
On1 offer PhotoRaw 2020, which is a lot like a combination of Lightroom and the photographic bits of photoshop in a single package and works well.
DXO offer Photolab, which is a more automated package for image development only.
Capture1 offer a development package that is powerful and very well thought of but extremely expensive.
Luminar have an image development package that many here like and use (not tried it myself yet).
There's also free development packages like Raw Therapee and Darktable that tend to be less refined than commercial packages but still very useful.
Finally there's usually free software from the camera maker themselves (not sure what Fuji have).
There are excellent resources available in terms of reviews, previews and tutorials on youtube, and all the above will normally let you download and try the software FOC for 30 days before it must be registered.
Also RAW or JPEG - my opinion is that you should always work in RAW, at least at first, because it's like a digital negative that will offer much more room for helping correct mistakes/deal with difficult situations and offer more flexibility when processing. JPG files are more like the prints you used to get from boots, and have much less latitude over things like exposure, highlights and shadows, colour casts etc. An experienced photographer can work with the cameras limitations to get the JPGs they want, but when you're starting out they can be a bit disappointing.
