If we separate the culture for a bit and think in terms of races themselves, a couple things can easily appear. And then the culture can be remolded to make more sense. I'll try to give my take on some.
Kitsune - of course tricksters and shapeshifters, loving to fool around with you and NOT xenophobic. Most are sociable and willing to help, but some being malicious or even plain evil. May prefer monogamy and nature. Honestly CoC ones were a serviceable base for development. The world is their plaything.
Lupines - ferocious and territorial, but get friendlier once the community accepts you. Strong oral tradition and a firm sense of justice. Predatory nature means they need to get off some of that steam either by brawls or fucking. Most would probably be nomadic? They'd rather build communities than conquer.
Catfolk - laidback smoothtalkers, not interested in getting their hands too dirty. They easily meld into other communities, but once there, some are known to cause trouble and crime, not rarely becoming gang leaders or just shady entrepreneurs. Don't need no temple of harlots as most are quite promiscuous. They would probably take over countries if they didn't compete so much.
Lizardmen - I immediately thought of Argonians, admittedly. Using their aptitude for water and sneaking, they're great explorers, assassins, hunters and scouts. Assuming they lay eggs, children could either be raised by parents, forming strong connection, or more often by the community, leading to greater solidarity. This may also mean that they are of few words, while meeting others, since outsiders are almost never on the same level of familiarity. If possible, they travel outside in groups, settling in damper regions. Being in the cold region makes them sleepy, almost lethargic. (also they didn't even bother to make a race description for Pavo's race)
