The resource argument seems a stronger case for why polygynous arrangements might choose to limit family size;
in most cases where polygynous relationships have occurred (less advanced societies, certain segues of the Mormons, various cults) the men are the sole or primary breadwinners,
and the additional wife/wives already represent additional consumption on top of whatever children eventually arrive.
Besides that, the fertility rate among monogamous couples in all societies seems to be correlated inversely to an increase in general wealth and women's rights more than anything else.
