still, i am exclusively use xfs where there is no diverse media under the system (satasas only, or ssd only), and had no real problem for decades, since its simple and its fast.
the proxmox team works very hard to make sure you are running the best software and getting stable updates and security enhancements, as well as quick enterprise support. Tens of thousands of happy customers have a proxmox subscription.
My own tests on performance are pretty good (better than ext4 for this specific setup of old hardware and cf media). Various tests around the internet demonstrate extended life specific to emmccfsd type devices, so thats nice (cant really verify these for myself, but the performance is nice still).
In general, ext3 or ext4 is better if an application uses a single readwrite thread and small files, while xfs shines when an application uses multiple readwrite threads and bigger files.
When looking at fragmentation, do not forget that ext4 supports a maximum 32k blocks in an extent, which at the default 4kb block size is 128mb. As your benchmarks show, does not appear to be a performance limitation. What would be more interesting is rerunning the benchmarks on an aged filesystem and compare how performance degrades with age.
so i normally recommend a normal setup with ext4, if you dont want to store much data. My way for setting up proxmox is a bit different - i am setting up a normal debian, because at this way i can create my own partition schema on the disk.

proxmox ext4 fs error on r210ii with four ssds i am running proxmox on a dell r210 ii, which i recently upgraded to use four kingston a400 ssds running in raid 10 using the h200 raid controller. After this machine ran for a few hours, it encountered an error and fell back into a read-only root filesystem (ive seen some answers that suggest.).
