Maybe like this: Put 5 (or some other number of) control points on the map. They're a bit like construction sites, but with no buildings to construct, and the type of unit that can claim them depends on the terrain.
When your side gains control of 80% of the control points, a countdown starts from 60 seconds. If your side loses that control, the countdown ends. When control is more than 80%, the countdown goes at double speed. Completing the countdown wins the battle.
Air control points? Maybe not, no more than 5% of the map's control points. Far easier not to have it, both visually and logically.
Pure naval battles (no land in map): Naval control points only.
Pure land battles: Land control points only.
Land battles with lakes/sea: 0-20% naval control points.
Naval battles with land: 0-20% land control points.
Island/coast battles: 50-90% land control points.
More important than the numbers: Using control points, most land territories should be winnable with ground units only, and all ocean territories should be winnable with naval units only.
GUI: Include with the tug-o-war display of military strength (coloured bars on top during RTS) a similar indicator of the number of control points held, contested/unclaimed control points being a white space inbetween. (Left team x% | contested/unclaimed | Right team x%)
