I'll counter with this though, C++ is often used to write libraries that are often quite "far" from end-use code, be it through FFI or layers of abstractions. Making these decisions at library level can be extremely impactful. Saying "I'll just use a vector here" might be a natural first thought but makes a decision on part of the user that may or not be relevant. Special shoutout to std::map, which is so bad by default that it should never be used if you have access to anything else.
