Togepi line based on pokedex entries.
Audino in a medical sense, since it can gauge how one is feeling.
Skitty because of its cuteness and how popular its cuteness makes it in-universe, likely both cheering up the owner and drawing other people to them like how people meet walking dogs.
Bad: Cubone. Attitudes are contagious, and you'll be stressed to find a pokemon more depressed than this one.
Yamask, this is what you will become one day, and it sometimes cries while looking at its mask.
Banette. Literally a doll animated by hatred. Will likely play devil's advocate and drive you to self destructive things akin to a voodoo doll sticking needles into itself.
Alolan Meowth line. Superiority complex means they'll probably treat you like crap and think you're their slave. Likely normal Meowth line, too, though definitely to a lesser degree.
Gloom is bad, I mean, look at the name. The bad smell will likely drive the person with depression insane and its constant sad expression probably won't help.
Generally speaking, the higher their base friendship is, the better they are.
Notably, Rockruff could go either way because of the period of time where it gets rebellious. Lycanroc generally would be good, though, especially midday.
