The differentiation between CDT as a decision theory and FDT as a policy theory is very helpful at dispelling confusion. Well done.
However, why do you consider EDT a policy theory? It’s just picking actions with the highest conditional utility. It does not model a ‘policy’ in the optimization equation.
I suggest the paper I mentioned on sequential extensions of causal and evidential decision theory. Sequential policy evidential decision theory is definitely a policy theory. But sequential action evidential decision theory is a decision theory making slightly weaker assumptions than CDT. So it’s not clear where the general category EDT should go; I think I’ll update the post to be more precise about that.

Also, the ladder analogy here is unintuitive.
