Yay!
As you would expect, there will be those who will fight against it - religious conservatives. It was ever thus, as we can see from this article at National Catholic Reporter ...
Women are on the verge of constitutional equality, but some Catholics still stand in the way
[...] The ERA was so popular in the 1970s that many expected it to pass. Even some U.S. bishops were in favor of it. Six members of the U.S. bishops' conference formed an ad hoc committee on women in church and society to support the amendment in 1978.
In the end, the U.S. bishops rejected it "because of uncertainty as to its legal and constitutional consequences for family life, the abortion issue and other matters." The bishops were lobbying for a constitutional amendment to limit abortion and, they claimed, their legal counsel had discouraged them from supporting the ERA.
The U.S. bishops, of course, were not powerful enough to neutralize the ERA. But one very conservative Catholic woman was: Phyllis Schlafly. A constitutional lawyer, radical anti-feminist and anti-abortion activist, Schlafly was a culture warrior before the U.S. bishops knew it was cool. Her grassroots movement called Stop ERA (now known as the Eagle Forum) is largely credited with convincing lawmakers to reject the amendment.

"The Equal Rights Amendment hurts women — both born and unborn," the Virginia bishops wrote in a press release in early 2019 as a surging Ratify VA campaign was getting serious traction ....
I find it hard to understand why any woman would want to belong to the Catholic church, which denies women equality within the institution and works via lobbying to doom women's rights in the greater world as well.
