is the mechanism for finerenone/kerendia sufficiently well understood such that it would be understood as to whether it would be good/not good for people who are do not show any symptoms of heart disease. would the drug be prophelactic in this case?

I would think there are known, healthy options to reduce cardio issues I would encourage, before something like this. There is no end to the items one would need to take to prevent various unknown maladies for the future, when we aren't showing symptoms.
Just eat, sleep, and exercise in healthier ways, supplementing what is practical and doesn't cause problems with other things you are also taking.
I joked with a relative who had a serious injury that we should have him constantly wrapped in bubble-wrap for the rest of his life. That would be helpful—but not practical, nor socially acceptable.
