This seems rather micro intensive, and somewhat time intensive, so I don't see it being a huge deal, but I may be overlooking something.
The way it's typically worked for me was this:
Warp the main fleet in (acquire agro at wormhole and, more importantly, suck up tractor beam slots at wormhole).
Wait 2-3 seconds, warp T-Raiders in.
Jump the T-Raiders to just outside of tractor range at each guard post and wormhole around the system. There's a slight (half a second or so) delay between teleports so this takes about 10-15 seconds.
Jump the T-Raiders back to the main fleet to help with beachhead cleanup.
By this time, most of the AI units are sitting out in the open (away from tractor beam support). So now I send my main fleet toward their first target (usually a spec ops but whatever else floats my boat).
Grab the T-Raiders and start picking off the groups of 5-20 bombers / Cruisers that are now defenseless in space.
200+ T-Raiders will generally instakill up to 20 bombers of similar level so this process takes from 10-30 seconds depending on the unit mix.
Finally, I park them on whatever cluster of Anti-Startship units are bearing down on my main fleet.
It's really very little microing since I'm doing it while my fleet is moving between targets.
