It seems like being more religious is more effective at changing minds than any of those policies.
"High" is very relative, France is still well below replacement fertility despite all their efforts.
Meanwhile very religious groups like the Amish have much higher fertility rates without any of those interventions.
Maybe a deep belief that god wants you to have kids is just much more effective than any policy?
From the article I quoted:
> Since the early 2000s France has consistently topped European rankings. After two decades of decline, in the 1970s-80s, the fertility rate started picking up again in the late 1990s. Since then the country has registered scores just short of the mythical threshold of 2.1 children per woman, which would secure a steady population. Its fertility rate in 2014 was 2.01.

The United States has had a higher fertility rate than France and Europe for many years despite having a notoriously porous social safety net.
The stats may change but whereas Europe has been below 2 for a long time, that's a more recent development in the United States.
The article states the opposite of your claims:
> The fertility rate is high in European countries where family norms are flexible, women feel free to work, pro-child policies are generous and childcare is well organised – in short, in countries that have come to terms with gender equality.
