Why cruiser officers had to be the sensible ones

Why do fewer famously eccentric senior officers seem to have come from the cruiser service than from destroyers or submarines?

Cruiser officers often had to conduct diplomacy and deterrence independently, roles that rewarded restraint and sensible judgment.

The question contrasts colorful officers associated with destroyers and submarines with the apparent shortage of cruiser equivalents. Cruisers routinely performed missions where restraint and judgment mattered. An officer representing national power abroad had to manage diplomacy and deterrence without turning every encounter into a crisis. Cruiser command therefore selected for a different public style even though it still demanded initiative and independence.
