I don't fully agree for two reasons.
First, I am not sure the data on most in-use hardware (e.g. EC2 m5/c5/i3en etc ...) supports your conclusions. xxHash is faster than crypto hashes always and BLAKE3 single threaded is faster on every Intel machine I've come across in wide deployment. I hear similar arguments around CRC-32 and to be frank it just isn't true on most computers most people run things on.
Second, many languages don't properly use the hardware instructions and if they do they often don't use them correctly. For example, Java 8 has bog slow SHA-1, AES-GCM and MD5 implementations, and switching to Amazon Coretto Crypto Provider (which is just using proper native crypto) was able to speed SHA/MD5 up by 50% and AES-GCM by ~90% on a reasonably large deployment (although the JDK wasn't using proper hardware instructions for AES-GC

M until Java 9 I think it is still slower even after that).
That being said, like I disclaimed at the top of the benchmark your particular hardware and your particular language matters a lot.
