> it's clear from research that users prefer custom buttons if they provide more "features" than the defaults.
Hate to be asking for a "source", but what research? And what "features" can a radio button even have? You click it and it's selected. I suppose accessibility can be considered "features", but I'm strongly suspecting that the overcomplex button has worse accessibility.

Well, this is true in a sense, but it's not exactly a good argument for re-implementing all that complexity in JS / HTML, instead of simply using the browser's implementation that's written in a real language.

Accessibility is incredibly hard to get right, particularly managing screen reader announcements, focus management and form validation. I recently had to build a website that met WCAG 2.1 requirements and it was made significantly easier by using React Aria (https://react-aria.adobe.com/) which is a similarly complex headless component library. To get an idea of the work that goes into making an accessible component, see their blog post about making a combo box where they test 4 different screen readers x 4 different browsers: https://react-aria.adobe.com/blog/building-a-combobox
(I haven't used Radix so I'm unsure how well they do a11y)
