May I ask which software program you are using to process the images? If it is Lightroom, drop it now like a hot potato! LR is great for all of the camera brands including the Fujifilm GFX series that use a Bayer sensor, but X-Trans is awful in LR. Until I switched to Capture One, I was ready to sell my Fujifilm gear. The watercolour look was horrific, nothing looked sharp. When I switched to Capture One it was a 180° turnaround. My standard sharpening for Fujifilm is 140-180 per cent at 0.8 pixels and noise reduction at 0 Unless shooting above 1600 iso. Been a pro photog for over 35 years and will vouch for my claims.
Right now the only thing I am doing is downloading the pictures onto PHOTOS on my iMac.
I am not doing any post processing, but did have to play with a lot of pictures from my last holiday, as they were all way too pink.
I have mentioned this before, but my iMac is 2011, and on its last legs. I know I need a new one, but I think an iMac update is imminent with the new M3 chip, so I am just trying to hold out until then (although touch and go if my computer, or patience - will hold out).
My current iMac is fine for emails, browsing, excel and word - but it is not coping with more than that - so I haven't downloaded an imaging processing package. But when I am ready I will go with Capture One.
For now - I would just be happy if my Fuji jpeg pictures were at least as good as those from my iPhone, and I really expected them to be.
I know that quite a number here suggest you use RAW and process from there, either in say LR or Capture One, but really there is no need for that while you are concentrating simply on getting good results from a new camera ... There is absolutely nothing wrong with using JPGs and the film simulations.
You've previously shot with film SLR & DSLR, as I have from way back in the 60's, and I would be tempted to firstly do a full reset, then use a JPG setting, whichever size you prefer. On the AF/MF page make sure PRE-AF is OFF, and I would switch off Touch Screen mode (Page 3?) to avoid accidental nose swipes !
Set HIGH ISO to -4, and sharpness to +1. Clarity to zero.
Personally, being old school, I use single AF, with a single point, and adjust the focus box size according to the lens I am using and the subject ..
I use MULTI metering, and that works for me on my XT2 and XS10 - I find it entirely predictable, although I hear that the XT5 might behave a little differently.
The QUICK menu is worth spending time on, as that will give you easy access to settings you will commonly want to use, and it is entirely customisable. In DISP CUSTOM SETTING you can select the options that you want visible eg Histogram, Aperture / S Speed, White Balance. If its cloudy when you're out there, use the CLOUDY WB setting ...
With my either of my bodies set up in this way, I can happily click away knowing that the JPGs will turn out pretty well, without the need for much editing, apart from cropping and adding contrast or saturation ..
Here are some snaps I've taken in the past few days in JPG mode, using the 90mm & the 16-80
