Try making the window chrome bigger on macOS. You can’t do it.

You absolutely can do this: https://support.apple.com/en-il/guide/mac-help/mchl86d72b76/...

That isn’t an actual solution as it requires running the display at a non-native resolution and thus seriously compromises text readability. It’s basically just low tech digital zoom.

I want to make things bigger in pixel resolution, not make pixels bigger.

It's enough of an actual solution for Apple to have been using as all of their best-selling laptops' default setting since they switched to Retina in 2012.
