You can specify plenty of columns in whatever order you like:

Available columns:
       NAME  device name
      KNAME  internal kernel device name
    MAJ:MIN  major:minor device number
     FSTYPE  filesystem type
 MOUNTPOINT  where the device is mounted
      LABEL  filesystem LABEL
       UUID  filesystem UUID
         RO  read-only device
         RM  removable device
      MODEL  device identifier
       SIZE  size of the device
      STATE  state of the device
      OWNER  user name
      GROUP  group name
       MODE  device node permissions
  ALIGNMENT  alignment offset
     MIN-IO  minimum I/O size
     OPT-IO  optimal I/O size
    PHY-SEC  physical sector size
    LOG-SEC  logical sector size
       ROTA  rotational device
      SCHED  I/O scheduler name
    RQ-SIZE  request queue size
       TYPE  device type
   DISC-ALN  discard alignment offset
  DISC-GRAN  discard granularity
   DISC-MAX  discard max bytes
  DISC-ZERO  discard zeroes data

With udev, You can use

ls -l /dev/disk/by-label

to show the symlinks by label to at least some partition device nodes.

Not sure what the logic of inclusion is, possibly the existence of a label.

There is a blkid command which may be what you are looking for. Results are similar to the following:

$ sudo blkid /dev/mapper/vg_rootdisk-lv_var
/dev/mapper/vg_rootdisk-lv_var: LABEL="LV_VAR" UUID="08520908-03cd-4e42-a4e4-0f5a771be16c" TYPE="ext4"

One other option is to use the udevadm command, which likely will give you far more than you need:

$ sudo udevadm info --query=all --name=/dev/mapper/vg_rootdisk-lv_var
