Did it work? If so can you make a note on the github issue please? rclone does not mount on freebsd-14-current · Issue #5843 · rclone/rclone · GitHub
I think the ultimate cause is fuse lib is broken on recent FreeBSD · Issue #280 · bazil/fuse · GitHub which using cmount
works around as it uses a different Go->FUSE binding which uses libfuse directly.
