Aragorn's endgame was to head to Gondor with Boromir because he believed that the dreams Faramir and Boromir had were a summons for him. However, he believed Gandalf probably had no concrete plans past Lothlórien.

I do not think that even he had any clear purpose.

As for Aragorn's part in now bearing Gandalf's burden as leader of the Company he would follow the Ring, "yet what help could he or any of the Company give to Frodo, save to walk blindly with him into darkness?" [p. 435] So I'd say Aragorn had no plan on how to get into Mordor or to distract Sauron. Though Boromir did suggest they should go with force into Mordor rather than sneak in as they were, but not necessarily to destroy the Ring.
