The ranged Hair Trigger operative and the ranged Overwatch soldier are the two strongest martials in all of Path/Starfinder 2e by ~8th or ~9th level, once they pick up an energy damage module.

The witchwarper is the strongest caster in the entire system by 10th level with Twisted Dark Zone, and then the single most game-breaking character possible by 18th and 19th level with Complete Transposition and warped infinities.

The envoy and the solarian, in contrast, are mostly so-so in terms of power level.

If I had to assemble an all-star team with all available material, from 1st to 3rd level, the backbone would be a flying-ancestry reach fighter with Sudden Charge. By ~8th or ~9th level, a ranged operative with Hair Trigger and a ranged soldier with Overwatch would be the strongest martials possible. By 10th level, Twisted Dark Zone is easily enough to make the witchwarper the strongest caster in the game. For an in-combat healer, I would gravitate towards a cleric, though I could also see a case for a mystic.
