I was suprised the degree to which selector performance is a negligible overhead in normal use these days. Was browsing through the docs for some Vue+CSS library or another recently, and the author had done quite a lot of research into this, was interesting. They were heavily using the square bracket html-attribute selector notation, although I'm not sure if it performs better now, or if modern processors are just that much faster.
