Are wealthy white suburbanites generally socially liberal or conservative?

[100% pro-life no matter what]

Depends on where in the country.  But they mostly run the gamut on social issues (i.e. abortion, religious liberty) but are left of center on cultural issues (i.e. immigration). That's why these voters reacted worse to culturally conservative Trump than they did to socially conservative Bush 43.

Also, contrary to popular belief, evangelical conservatism tends to find its base in the suburbs and among the middle and upper middle classes.

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.
