hmmm, I'm guessing this is the author's "best girl" trio.

Because Claudia is clearly best girl.

I can't see any other connecting thread between them. Not personality/plot role/backstory/build, nothing.

Maybe. Or just that they're "side heroines" following the "main heroines" theme from the other trio.

Sure, but they're pretty random side-heroins at that.
I mean they're not even the "main" side-heroins/love interests, which would be the "short" group: Sasamiya Saya, Kurogane Shizuku and Saionji Usagi.

If you avoid reusing the Main Heroines, there can be various trios since the girls' personalities, physiques & statuses don't perfectly align:
Buxom Suductress Trio Attempt;
Short Buxom Trio Attempt;
Short Flat Chest Trio Attempt;
Imouto/Kouhai Trio;
etc.
