How do I remove code duplication between similar ref-qualified member functions?

One thing you can do is you can implement the logic in a non-member function and take the type of *this as a template parameter:

class MyStringBuilder
{
    std::string member;

    template<typename Self>
    static std::string create_impl(Self&& self) {
        // Some work
        std::string result = std::forward<Self>(self).member;
        // More work
        return result;
    }
public:
    // Other functions
    std::string create() const& {
        return create_impl(*this);
    }

    std::string create() && {
        return create_impl(std::move(*this));
    }
};
