@Salubri

How about adding another category, for Shinigami in general:


 * Extremely long lifespan: Shinigami age, but very slowly. Nimaiya, who invented the Zanpakutou and likely is >1500 years old (I base that on Yama's comment to a young Shunsui, that Yama used to be a "monster"  a long time ago  - showing a picture of him using Ryujin Jakka), didn't appear older than 40-45. Unohana looked no older than 25-30, even though she'd been around for >1000 years. It's not unreasonable to guess that a Shinigami's lifespan is around 40 times longer than a human's.

 * Object-Dependent Immortality: your immortal only so long as a specific object exists. (but if destruction comes to the object then there goes ones life or they may require constant usage of said object to maintain immortality).

I agree that, out of the five examples you provided, this seems like the most accurate definition of Aizen's current status.

 * Immortality: never age and basically recover from any physical injury. (still may have a specific weakness like decapitation or disintegration or a power that steals your immortality)

Come to think of it, Ichibei got decapitated by Yhwach earlier, and somehow survived. Doesn't that accomplishment warrant some  "immortality points" ? ^^

That's true, and is supported by the fact that Mayuri had to kill many Souls in SS, to keep the balance between worlds, when the Wandenreich army went on a rampage in Hueco Mundo. The Soul King never interfered in that instance.
