The most commnn use for me is the art history term for a circular,
decorative panel (della Robbia inevitably springs to min), but AFAIK
it's used for anything that's round.

I suppose, but it's more likely to be called a "rotunda".

TfL call it a "roundel" because that's what it is.

Note for further discussion.
According to that 'page' not all roundels are round witness American
(US) stars and bars and Russian stars

I suppose the US symbol is a roundel with wings - which isn't a bad notion.
