The top option of "Hard-Working Settlers" ("Immediately Ravage in the land with the most Invaders that matches a Ravage Card.") works in a similar way: players aren't choosing a Ravage Card and finding the most-populated land matching that card (allowing them to choose a card with a favorable Ravage); they're looking at all lands that match at least one of the Ravage Cards and finding the most-populated land amongst all of those lands.
Don't forget effects that change which lands match each card! For example, "Competition Among Hunters" (The Tsardom of Russia Level 3) makes lands with 3+ Explorers match all Ravage Cards, such such lands
don't count as lands "not matching a Ravage Card" unless there are no Raavge Cards. Similarly, if "Weave Together the Fabric of Place" joins two lands of different terrains, then that land only counts as not matching a Build Card if neither of its terrains match any of the Build Cards.
