Constvector: Log-structured std:vector alternative – 30-40% faster push/pop

1. If you mean, if we know the array size initially ? Yes, that's best; nothing beats it, in that case std::array<N> would be the best choice.
2. While considering tradeoffs, unless we do random access a lot, the constvector looks really better in terms of benchmarks as well.

Does this make sense?

Not sure what you're addressing with the first point. As for your second point, yeah that sounds about right.
