In 2020 Pat Symonds said they were studying the possibility of using 2 stroke opposed piston engines for the now ill-fated 2026 regulations.

Symonds argued that the direct injection, pressure charged OP2S were not only more efficient, but also environmentally friendlier as they have lower emissions than 4 strokes.

This power unit would have been light, but one thing no one ever answered was how they would be packaged, as far as I'm aware they'd run in to the same packaging problems flat engines had.

In theory such power units would have made the cars themselves greener than Formula E cars, which is an interesting fact I just learned.

I find this alternative reality where F1 switched to two strokes super interesting, here's an article about it from back in 2020: https://www.motorsportmagazine.com/articles/single-seaters/f1/two-stroke-engines-eco-fuel-f1-aims-to-be-greener-than-formula-e/
