Some information about army disposition wouldn't be a bad thing. In addition to task ("this army appears to be patrolling"... caveat: you can't get information like "this army appears to be tearing down its camp and getting ready to move" since by the time the report comes it would already have moved. On the other hand, "these forces moved to..." would be reasonable, assuming non-stealthy forces of significant size.), some things might be more widely known ("the famous champion X is rumored to be here") et al.

One could make a case for money making a difference, but only within limits, and perhaps based on dominion and unrest -- a province that hates its ruler is more likely to help potential invaders, especially if they worship that invader's pretender.

Information about province conditions would make some sense, but bear in mind that a province might be far larger than a battlefield, and that it could well have rather varying terrain within it. So, without finer detail in the movement system, it would be difficult to use terrain info to figure out where a likely battlefield would be and what it would be like. While more detailed movement could be a good thing, it would be a rather huge change I'd say; perhaps in a total rewrite, if then.
