In the phase of Manual Partitioning in the UI where a person is building the storage configuration, what does the "Label:" field actually do?
More specifically, why use it if it is not required at all?

Re: Manual Partitioning - Label
It allows you to add a label to the filesystem which can then be used in /etc/fstab to mount it via LABEL=
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

Re: [SOLVED] - Manual Partitioning - Label
The enumeration of devices is not deterministic. Some filesystem types can contain metadata "label". Persistent identifier (and hopefully unique). That lets you always mount that filesystem correctly regardless of the enumeration.
Filesystems do have UUID too, for same purpose. UUID is usually autogenerated, while LABEL is more "human" name. IIRC, the (support for) LABEL did appear a bit earlier than the UUID. See:
If you clone whole disks/partitions (or mirror breaks), then you have two separate entities with identical LABEL and UUID. That is not fun.
