There are some interesting cases. It took a long time for men to break into synchronized swimming, where women typically have the advantage. Archery still has some strength elements that could be relevant, but shooting should be pretty egalitarian and is still split, as far as I know.

I have never been particularly into sports, and stopped watching the Olympics very much when the amateur requirements were relaxed (when hockey was dominated by NHL stars). There may be some nuances I'm missing, and there is also the aspect of making a sport/competition more welcoming to women, such as women's chess. While those are interesting social/cultural aspects, they have much less bearing on capabilities of a given sex/gender.
