CATO's numbers also match the Post's. They did a 2013 follow-up study to a prior 1995 study they did of work vs welfare trade-offs on a state by state basis. There is probably no more comprehensive source than their study, that I'm aware of.
"this study seeks to determine the approximate level of benefits that a typical welfare family, consisting of a single mother with two children, might receive"
[34 states come in above $25,000]

Here are two articles that dig into how the Cato numbers are technically possible but not useful for having a real dialogue about the benefits people wind up receiving in real life:
