One can even try to derive things directly from expected utility all the way to actions but the mathematics gets pretty complex quickly (I did some work on this in 2015 and am sitting on a draft paper that someday somewhere I’ll publish. It is beyond my current ability to efficiently explain clearly to a large audience.)
Other perspectives that are arguably missing or extensions that can be done are:
Side effect analysis and modelling the entire future trajectory (generalizations of these can be created):

Specialization for a particular problem, with ensuing accuracy improvements can be done by causal analysis, Fermi modelling, Bayesian modelling, and inspired by https://forum.effectivealtruism.org/posts/zdAst6ezi45cChRi6/list-of-ways-in-which-cost-effectiveness-estimates-can-be
The value to action chain idea can be used to substantiate value more clearly: https://forum.effectivealtruism.org/posts/Ekzvat8FbHRiPLn9Z/the-values-to-actions-decision-chain-a-lens-for-improving
