Yep, Negative Nancy

I've sold images, not had complaints, even printed an X-T2 image onto A1 for a client (processed in Lightroom as well using the Adobe RAW converter!). There are plenty of wedding photographers out there using X series cameras, and even the likes of Thomas Heaton uses X series cameras for landscapes as well.
Fuji files respond best to gentle processing, its easy to make worms especially with over sharpening.
You have to remeber the gviewing distance for prints is often further away than that of a monitor, so ultimatec resolution is not 'normally' a worry.
