The thing missed in the video is that there would be no close flybys, unless both sides royally fucked up. The warring fleets would see each other across half of the solar system at least, much more if under acceleration. From there until the end of the fight, one would expect the space between them to be like one huge rave party, pretty much saturated with laser light.

Yup, with current technology, that would be the most recognizable part of any ship, as all interesting functional parameters of the ship itself scale with radiator surface area.
You’re assuming these ships have weapons. That may not be the case at the start of a civil war where both sides just have civilian craft. Or what happens when two prospectors booth find a very valuable resource. Even today in an age of nuclear weapons and drones etc, people still occasionally beat each other to death with sticks.
Rockets / drones / mines could be useful depending on assumptions such as how easy they are to detect. Having a laser or projectile hit your ship could make a huge noise etc.
Both sides may or may not have appropriate weapons, so some battles could involve ramming or aiming the engine at the other ship etc. Even just dumping junk out an airlock on a close flyby might.
