What we have is a list of proposed decision theories (Evidential Decision Theory, Causal Decision Theory, Timeless Decision Theory, Updateless Decision Theory), each of which acts the same on standard decisions, but which deal with Newcomb-like problems differently. Some of these decision theories satisfy nice general properties which we would want a decision theory to satisfy. There’s argument about which decision theory is correct, but also about what the various decision theories actually do in various situations. For example CDT is normally thought of as being the two-boxing theory that people intuitively use, but some people argue that it should take into account the possibility that it is in Omega’s simulation and hence it even people following CDT should actually one-box.
So the discussion is more nuanced than “What is the correct thing to do in Newcomb’s problem?”, it’s more “By what general criteria should we judge a decision theory?”. Of course any particular insight you have about Newcomb’s problem might generalise to this way of looking at things.
