I also like to use std::optional if a function may not return a result so I won't have to return a pointer, that might be a nullptr.
And std::variant as a typesafe less hacky union.

I agree, I'm also hyped by std::expected, though it's C++23, so it will be quite some time before we can use it in production but still, it can easily be added as it's just a class.
