Current answer
Rankings are not source-ready
The official description confirms 14 careers, cash and promotions. It does not name all careers or provide pay, requirements, promotion speed, skill effects or a basis for saying one option is best.
A confident-looking tier list would mix guesses with fact, so the launch version publishes the evidence boundary and practical comparison criteria instead.
Confidence: withheld until repeatable exact-game comparisons exist.
Source notes: official creator copy confirms the loop and career count, but does not publish ranking inputs.
