It’s ultimately under the umbrella of ideologies that support and prop up capitalism.

I think that's a good summary.

"Classical liberalism" is basically what modern libertarians want: a laissez-faire capitalist economy, a secular representative government with very limited powers, prioritizing individual freedom over collective well-being, etc.

In my part of the world "liberalism" is now commonly used to refer to a different set of priorities: creating economic safety nets, regulating business, promoting universal healthcare, unions, gender equality, racial equality, etc. Though capitalism and a secular representative government are still part of the mix.
