Excellent finding!
I think this is the key to a solution. The remaining questions are:
1. How to mount exFAT on FreeBSD?
I think I can answer that: A FUSE module is required. Install
fusefs-exfat (and maybe exfat-utils) from the sysutils category
to get mount.exfat and exfatfsck (if it should be needed).
Inegration with /etc/fstab should be no problem.
2. How to initialize a exFAT SD card on FreeBSD?
Probably with mkexfatfs from exfat-utils (as mentioned above).
