If you want to use all the software features of your Mac, your only option is HFS+.
It supported UFS up until 10.9, but that was ancient and awful.
It can read and write FAT, but that's even worse. (It doesn't even support permissions, so it couldn't possibly boot from a FAT volume.)
It can read and write FATX. I don't think that supports permissions either, though, and it's also annoyingly patent-encumbered.
It can read NTFS, but not write to it.
