At the end of the day, what really matters for most people is
1) Certifications (FIPS...)
2) Speed.
SHA-256 is fast enough for maybe 99,9% of use cases as you will saturate your I/O way before SHA-256 becomes your bottleneck[0][1]. Also, from my experience with the different available implementations, SHA-256 is up to 1.8 times faster than Blake3 on arm64.
