The answer does suggest that but it was incorrect.

PS I did google but couldn't find a free source for commercial use.

I don't know that there is a version of Century Gothic that is free for commercial use. I know the rights were owned by Monotype. I don't know if that's still true or not.

Here's a screen shot of Font Book from Big Sur. No Century Gothic.

Century Gothic was never included in macOS. It was included in Microsoft apps for Macs, such as Office and Word. Whether it still is I don't know.

You can do an online search for a free version.
