In general, the more different jobs you design a machine to do the more expensive each job becomes. Sometimes, the job isn't done as well.
Maybe they need a small vessel to destroy other ships, and a more lightly armed, more heavily manned vessel for policing space. Something conceptually like the Coast Guard Cutters used for convoys escorts in the North Atlantic. After all, they won't be scouting for a fleet, or helping screen SDs.
Actually, the F-15's original design motto was "Not a pound for air to ground". The F-16 was designed as the low cost "Do-it-all" plane, especially aimed at the export market. F-15s did evolve into the all weather multi role plane in the F-15E variant (which was re-designed to fit a medium bomber role), but this was 15 years after it's debut, and not a role originally intended for the airframe.
As for the Honorverse, the question you bring up gets down to what the navy is intended for. Most navies are not intended to exert power outside their home territory - this is why many of these small navies are LAC based. And in these cases, your normal roles are maritime patrol, pirate defense, and SAR - none of which require large crews. These navies go home at night or after a multi-day shift; if they need more resources, it can show up in a couple hours. Navies with a regional presence require larger crews and more firepower.
A ship in a regional navy can't rely on another ship for assistance, and must do everything with it's resources. If they take a prize, they must man the prize and protect the prisoners. a single system polity can just send another LAC with a Prize crew to meet the captured ship.
Hyper warships can be part of either navy, and usually are on more extended missions that need to be self-reliant. But are they? This design philosophy is seen in surface warships today. a US destroyer has more mass dedicated to living conditions and fuel, because a US ship needs to cross the Atlantic or Pacific to get to it's patrol zone (and back). A European ship has less space dedicated to the same because their patrols are usually in or near home waters, and are shorter as a consequence.
The Polish navy was gifted a handful of outdated US Frigates about 10 years ago - the new crews loved them, specifically for their crew amenities and large spaces compared to the older Russian and European built ships in their Navy. Their old American crews hated them, finding them cramped.
What you build and buy is tuned to your navy's needs.
