I'm curious about what her future talk is like (bolded part). I know ESFJs who discuss what needs to be done, but it is practical and not in the far off future. Is your mom (it's your mom, right? ) talking about far off future goals that are conceptual and more vague, or is she discussing more immediate concerns? Of course, any type may do a little of both, but it's important not think all future talk = iNuitive.
Her annoyance with details does suggest N, but more info is needed. My ESFJ grandma sounds like a more balanced version of this - she is not that detail-oriented for work because she's more people-oriented. However, she likes to know details about people/events.
