In Gates onward, levitating pokemon (not strictly flying) get the ability to traverse the "walls" (floorless air) of mountainous/outdoors dungeons too, but not a single starter can take advantage of this either (not even with evolved forms).
As for fire, there's maybe one volcano dungeon in each game with fire tiles, two if you're lucky.
Meanwhile, especially in the earlier games, some postgame dungeons spawn items surrounded by water tiles.
The imbalance across starters is kind of painful.
