It was believed at the start of the war that they had moderate value as positions for basing or logistics but that's now questionable. The burden of picketing system might outweigh any benefits of location, wormholes aside.
I would also say that when the war is in the grinding attritional phase each system you captured not only took it's resources away from the enemy (and kept it from supporting light forces that might try to interdict your supply train if you left it uncaptured) but it gave you a chance to create a localize concentration of force to generate a favorable ratio of damage or destruction on the enemy fleet.
Politically they often couldn't abandon an occupied system without a fight, so it forced them to engage when you had an advantage (and sometimes if you pulled off a good surprise a much more overwhelming advantage than they suspected before you brought them into range).
But I'll go a step further and point out that it's quite possible that this goal wasn't the most efficient way to make war. (And having to defend the systems afterwards, even minimally, certainly did lead to some strategic disbursement). But keep in mind that nobody had ever fought an interstellar war on anything like this kind of scale. All the strategic thoughts on how to carry it out were untested theories until exposed to the crucible of this combat. (And that's even ignoring how the tech had changed since the last major interstellar combat)
So it wouldn't be surprsing if the system by system grinding advance turned out to be less effective that the pre-war theorizers thought. It'd hardly be the first time (WWII strategic bombing comes to mind). The mobility of fleets through hyper (and difficulty in detecting that movement) means that it's quite possible that a better strategy would have been to take the system, hold it long enough to systematically wreck all it's orbital and deep space mining and infrastructure, and abandon it beyond a light scouting presence warning you if the enemy attempts to rebuild (and possibly some randomly timed BC/CA sweeps looking for convoys trying to trade to get planet-side resources)
You'd still probably want to grab a few advanced system (whether captures from the enemy or simply unoccupied systems within their territory) as defended repair and resupply nodes as you pushed your Sherman's March closer to their key systems - but that's a far cry from occupying every system you defeated.
Heck the wrecked system's political demands for renewed protection might well divert useful amounts of the enemy's fleet and resources towards them. Whereas if they're captured then the enemy can write the less productive ones off until the fortunes of war change.
