ujm >> presumably, you know the source for Emunas Chachamim.
In a Baraita in a list after Derech Eretz and a good heart? I would refer you to 2007 Essay by R Nachum Rabinowitch “What is “Emunat Ḥakhamim” where he defines Emunas Chachamim to include a very respectful attitude towards halakhic rulings, and a requirement to understand the reasoning behind them, as the individual himself remains responsible for his action (more so in divrei reshut, if I understand him correctly). Many people use Daas Torah somewhat differently. I am not learned enough to know whether Chasam Sofer meant that.
It is also not my intention to analyze Arizal, I’m busy understanding pshat to be so presumptuous to weigh on kabbalah. I thought you asked that question. Unless there are tw2o ujms here (maybe a sitra aherah?).
