How to control the size of the inner dark circle of a radio button?

Short answer: you can't.

Long answer: you can hide the actual radio button and use css to create a "fake" radio button instead. There are plenty examples on how you do this, e.g. https://moderncss.dev/pure-css-custom-styled-radio-buttons/

You can't do this in a straightforward way. The radio button control is a feature of the browser used to read the page.

The way around this is to use some CSS tricks using before and after attributes of the button elements to effectively create a fake button, toggle or other similar control. You'll find lots of examples on the web if you search for something like "css style radio button" - like this list of 59(!) different things people have done with colours, shapes and images.
