Yes, the Nextorage NX-F2PRO 128GB SDXC UHS-II V90 is compatible with the Sony FX3.
The Nextorage NX-F2PRO is an SDXC UHS-II V90 card (not CFexpress, as a prior record wrongly labeled it). It fits the FX3 SD slot, and its V90 rating meets the FX3's stated SD requirement for XAVC S-I 4K (V90 or higher), so it covers every SD-recordable mode on the body.
“XAVC S-I 4K 600Mbps CFexpress Type A memory card (VPG200 or higher) SDXC V90 or higher”
“NX-F2PRO Series is compliant with V90 (guaranteed minimum transfer rate: 90 MB/s)”
