if you could pick a standard format for a purpose what would it be and why?
e.g. flac for lossless audio because…
(yes you can add new categories)
summary:
- photos .jxl
- open domain image data .exr
- videos .av1
- lossless audio .flac
- lossy audio .opus
- subtitles srt/ass
- fonts .otf
- container mkv (doesnt contain .jxl)
- plain text utf-8 (many also say markup but disagree on the implementation)
- documents .odt
- archive files (this one is causing a bloodbath so i picked randomly) .tar.zst
- configuration files toml
- typesetting typst
- interchange format .ora
- models .gltf / .glb
- daw session files .dawproject
- otdr measurement results .xml

At both algorithms’ highest levels, xz seems to be on average a few percent better at compression ratio, but zstd is a bit faster at compression and much much faster at decompression. So if your goal is to compress as much as possible without regard to speed at all, xz -9 is better, but if you want compression that is almost as good but faster, zstd --long -19 is the way to go
At the lower compression presets, zstd is both faster and compresses better
