exFAT is an extension of the FAT32 filesystem that allows for larger drive sizes and file sizes and is mostly used on SD cards. Despite the name similarities it has nothing to do with the ext filesystem, and won’t support the same features as it (such as symlinks).
Sadly, most of the ones I’ve found are too complicated, and getting all devices to accept the CA is more hassle than it’s worth for self hosting. I’ve given up and just buy my wildcard cert for 60$/yr and just put it on everything.
