If tested various Posix FS projects over the years and everyone has their shortcomings in one way or the other.

Although the maintainers of these projects disagree, I mostly consider them as a workaround for smaller projects. For big data (PB range) and critical production workloads I recommend to bite the bullet and make your software nativley S3 compatible without going over a POSIX mounted S3 proxy.

JuiceFS can be scaled to hundreds of PB by design, also is verified by thousands of users in production [1].

Agree, don't recommend POSIX proxy on S3 for complex workload, like S3FS. In the design of JuiceFS, S3 is like raw disk, JuiceFS metadata engine is like partition table, compare with local file system.
