Off the top of my head peeps with taur-specific scenes or includes some taur variations in TiTs: Edan on Tarkus, Amber on Mhenga and on your ship as a follower, Ellie on New Texas, Brandy on New Texas, Haley on New Texas, Dane on Zheng Shi, Jumpers on Zheng Shi, Urbolg on Zheng Shi, Forgehound on Zheng Shi, Rat Raiders on Zheng Shi, War Lion on Uveto, Milodan Males on Uveto, a few of the Extrameet dates, Sylvie on Canadia, Ushamee Neykkar on the Kashima Incident distress call and I think back on Canadia, Chaurmine who you first meet on Tarkus, Kelly on Tarkus, and that's all I can think of at the moment.
It sounds like a lot but I've done some female taur runs and you do either get blocked out of quite a few sex scenes altogether or the scenes don't take your taur status into account. Still I think it's worth to do a run like that, the saving grace being that it'll be a little quicker to get through because you can't fuck everyone. I did try a Naga run once and didn't finish because that had even less Naga-specific or Naga variation scenes.
Getting back on track with Coc2, yeah I understand why they're sticking to bipedal bodies for reasons stated by others. Still kinda sucks tho, I like having a reason to replay these games besides just restarting to see a new scene or dungeon that was added.
