Are wealthy white suburbanites generally socially liberal or conservative?

I don't think there's a way to meaningfully generalize them just based on being high-income white people living in suburbs.

There's going to be a lot of cleavage along what their education level is and how often they attend (Christian) religious services.

I mean, we can just look at Texas to see just how much these types of voters can differ depending on their views, the economic environment, polarization, and the candidates offered. \

First you have the Houston suburbs which are blood red. Characterized best by Montgomery county, you got the racial and religious factors at play here like in other Southern Suburbs. Heading North to Dallas, we find wealthy regions more in line with the Sun-Belt style trends of 2016.

The Uber-Wealthy regions like Highland Park are still red, but 2018 showed that the dems are now winning all of north Dallas and pushing North and west into places like Arlington and Plano. This trend seems to be more anti-trump and a rejection of the modern republican party, rather then true policy concerns.

Heading South we hit the Liberal Mecca of Austin. As we saw in 2018, Austin is expanding and those blue migrants are converting her suburbs. Migration of Democrats is the main driver here, and these people already have prescribed views. Wealth is therefore not the main demographic variable.

I'm skipping San Antonia, because its hard to get a read from a birds eye view on the wealthy whites in a region where most towns and precincts have significant minority population.

Whites in San Antonio have historically been very Republican. There's the effect of many of them being active/retired military, and the fact that the San Antonio area is the only part of Texas where there was a significant Republican tradition prior to the late 20th century. San Antonio doesn't have any major universities or other institutions that would serve as a "draw" for white liberals.

Both. Most Americans with very liberal or conservative social/culture views are wealthy white suburbanites.

In contrast, working-class people and ethnic minorities form a disproportionate percentage of people with moderate, more nuanced views on cultural and social issues.

Which is why I suspect democratic socialism would fix a lot of our vicious cultural/racial wars in the long-run (though not in the short-term, because we'd be bickering about disparate impact).

Yep.  Political partisans tend to be more affluent, on average.

Hence the quote about how the reason American politics is so off the rails is because one party is run by people who don't need anything from the government and the other is run by people who don't expect anything from the government.

They tend to be more liberal than the country overall. They’re culturally cosmopolitan and open to things like feminism, immigration, and LGBT rights. I think some southern rich conservatives may still be iffy on abortion, though.

Iffy on abortion?  Southern rich conservatives are overwhelmingly vehemently pro-life.  In fact, I would call that group the base/leader of pro-life movements.

It depends on their religious beliefs.

There are Episcopalian "country club Republicans" in the suburbs of Atlanta and Dallas who are personally indifferent to abortion and are fine with letting the pro-lifers have what they want as long as they get their tax cuts and deregulation.
