No, the Fujifilm X-T5 is not compatible with the ProGrade Digital CFexpress Type B Gold 128GB.
Fujifilm X-T5 storage media is SD/SDHC/SDXC only (UHS-I/UHS-II) per Fujifilm's own specifications page -- no CFexpress slot exists on this body. ProGrade CFexpress Type B Gold is a CFexpress Type B card, a different physical form factor that cannot be inserted.
