(Just FYI, there are two separate things here - one is autofit (which e.g. can be used by the player), and the other is what weapons the game decides are available for autofit to choose from when outfitting a specific NPC ship. There's quite a bit of RNG in the latter, and it also depends heavily on the faction *and* on the ship production quality, so seeing some poor fits in a vacuum is, unfortunately, missing important context.)
Edit: just to make sure, are these all from the latest version of the game? Some of these (the Paragon in particular), it's a little unclear how that would happen in the latest release.
