Which target Pal should PalRoutes explain better first?

PalRoutes is live as a scheduled Product Hunt launch, and I am using the pre-launch window to decide what to improve first.

The current version answers one narrow question: "I own these Pals, what is the shortest species route to my target Pal?"

It does not optimize passives, IVs, gender, or cake cost yet.

If you play Palworld, which target Pal would make this workflow most useful to test next? I am thinking about routes like Anubis, Grizzbolt, Orserk, Xenolord, Bellanoir, or late-game variants.
