What surprises me is the lack of an emoji with an unambiguous meaning of "thank you." I use the prayer hands but that seems to be implying something that doesn't quite fit. Raised hands is somewhat like thanks but also like, "that's cool."

Yeah, unfortunately that is hard to express pictorially as there's no universal human gesture or face for it (unlike most facial expressions). I have seen the clapping hands [1] use to say thanks, and alternatively the right-facing fist[2] (as in fist-bump) - but the meaning of the latter can be lost entirely depending on demography of recipient, or interpreted as being aggressive (I'll punch you), and the former might be understood to be applause.
