What is the ideal size for this container as I understand it's needed for VM and binary management?
Or can I delete or reduce the size of this container and what would be the ideal size, I can't believe it needs 14 TB

In the storage view, he first column is "FREE (Logical)" this displays available space for the container, the second column "USED" is space used by the container, in your case, the "NutanixManagementShare" is 0. and the third column is "MAX CAPACITY", which generally displays the available capacity for the container.
If you noticed your default and NutanixManagementShare are showing same "Free (Logical)" value, to understand in another way, the container is just representation of storage pool to the hypervisor and it is always thin provisioned, when the container is created you never specify the size of container, unlike traditional where you create volume and specify the size of volume/LUN.
