Couple of most sensitive data categorization are ‘Top Secret Ultra’ and SCI, ‘Sensitive Compartmented Information’ as defined in government/intelligent services.

In the business world, one of the most critical category is PII, Personally Identifiable Information. According to the NIST, National Institute of Standards and Technology, listed quite a few data as PII and possible PII, https://en.wikipedia.org/wiki/Personally_identifiable_information.
