Except you don't really want to break through an enemy formation unless you're pushing to take, and subsequently defend, an emplacement. Think Sovereign and the Geth attacking the Citadel in ME1, the only reason Sovereign broke through the defense fleet was to take the primary objective, i.e. the Citadel.
If you apply traditional Ship of the Line battle tactics to space you would have your larger, long range units further back engaging large and/or slow enemy units while your smaller craft closed and tackled those same and smaller units.
This is also determined by ship design. Ships of the Galactic Empire, and the Republic to a point, were optimized for head on attacks which was facilitated by their wedge shape. Both lateral and dorsal planes converged to a spiked nose allowing the maximum number of emplacements to engage at any given time.
Inversely, we see a very different combat practice in the re-imagined Battlestar Galactica, where main battery sections are divided by the quadrants of the ship. At any one time, even head on, half of the guns on any given Colonial ship are out of the fight. BSG also illustrates how relying on any one weapon type, especially missiles/torpedoes, can be a massive weakness. Had the Galatica had a proper supporting fleet, an abysmally small number of Cylon weapons would have ever penetrated the suppression screen.
This brings us back to tactics, in Star Wars we see much more static, or at least slow rolling formations with larger ships than we do in BSG where things are far more fluid. In BSG any given battle is more like a violent ballet than a "line up and fire" engagement with both sides trying to maneuver in such a way as to gain shots into the opposing ship's weak or vital areas. In Star Wars battles are matches of attrition with the most heavily armed and armoured slinging massive amounts of weapons fire at equally massive ships. Both of these combat styles are complimented and dictated by their respective ship design. In Star Wars Rebellion and CIS ships are better broadside vessels and have shields that allow them to survive the onslaught to close in. In BSG, Cylong ships have semi-smart missiles to make maneuvering slightly less critical.
TL;DR: Theoretically, the fit-out, composition, and design of your fleet(s) should determine how you'll use them.
