I would love to see a "favored of the wilds" choice that gave you nature proficiency and your choice of a druid cantrip. Then you could take shillelagh and build a WIS ranger.
The idea that there isn't a "Favored Foe: Beast Hunter" is crazy to me. A ranger who hunts dangerous monsters in the woods is probably the most iconic sort of ranger but you can't actually DO that currently.
Nature proficiency and a cantrip like Bonfire might be interesting for a beast slayer ranger. Or give them one use of Faerie Fire as a 1st level spell so you can track your beastly foes easier. Or heck, give it True Strike as a cantrip.
Then give Mage Hunter a spell that is more thematically useful to the slaying of mages like Detect Magic that doesn't use up a spell slot once per long rest.
The point of Larian's favored foe is to give your character a couple tools that show their experience and skill fighting a certain enemy that can be more widely applied to a lot of situations. This, to me, is how ranger should always have been designed. It is just a bit clunky in implementation currently.
