In his book Causality, Judea Pearl also argues in favor of CDT (though he doesn’t explicitly discuss Newcomb’s problem).
In case you just want to know why I believe support for CDT/two-boxing to be wide-spread among academic philosophers, see https://philpapers.org/archive/BOUWDP.pdf , which is a survey of academic philosophers, where more people preferred two-boxing than one-boxing in Newcomb’s problem, especially among philosophers with relevant expertise. Some philosophers have filled out this survey publicly, so you can e.g. go to https://philpapers.org/surveys/public_respondents.html?set=Target+faculty , click on a name and then on “My Philosophical Views” to find individuals who endorse two-boxing. (I think there’s also a way to download the raw data and thereby get a list of two-boxers.)
Yes, that’s the plan.
Some papers that express support for CDT:
https://philarchive.org/archive/ARMCDT-2
https://link.springer.com/article/10.1007/s11229-011-0022-6 (In general, James Joyce is a well-known defender of CDT.)

https://onlinelibrary.wiley.com/doi/full/10.1111/phpr.12466 (argues for two-boxing, but against CDT)
