As far as I know, the "remount,ro" does a complete flush, just as an umount does. So, yes, the fs-layer "umount"/"remount,ro" should make sure everything is on disk when it returns. ON addition, any meta-information (RAID superblock, LVM superblock, LUKS header) should be written to disk immediately after a change.
