ye i think that's most of them, if not all.
also a fun map that's not a conquest map technically but has a very unique gameplay is middle ages, here everyone starts with 1 base (or more if there's only 4 or less players), if you lose all your bases you're dead, even if you have troops left on other places. (makes for fun assasin/terminator games, especially with escalating spoils.)
operation drug war is also kind of a conquest map. (most of the regions start neutral and there's a few win conditions). steamworks has a lot of neutrals too, but i'd not really consider that a conquest style map. supermax prison riot also, not really a conquest style map, but has quite some neutrals.
oh and WWII Poland should definitely be on that list too.
