Star Trek captains as naval command types

Which naval commanders resemble Picard, Sisko, and Janeway?

Picard resembles Cunningham or Collingwood; Sisko represents a commander capable of markedly harsher action, while Janeway is linked more loosely to a contemporary training command.

The comparison uses fictional captains to distinguish naval leadership styles rather than identify exact historical doubles. Picard fits the composed command tradition associated here with Andrew Cunningham and Cuthbert Collingwood. Sisko represents a leader more willing to become severe when circumstances demand it. Janeway is linked more loosely to a contemporary training-command figure. The answer uses fiction to discuss temperament, professional formation, and the different kinds of authority a navy may need.
