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)

- photos .jxl
- open domain image data .exr

- 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
It would solve the long-form document problem. It wouldn't help with the editing however. The problem with HTML as it is today, is that it has long left it's document-markup roots and turned into an app development platform, making it not really suitable for plain old documents. You'd need to cut it down to a subset of features that are necessary for documents (e.g. no Javascript), similar to how PDF/A removes features from PDF to create a more reliable and future proof format.
Weasyprint kinda is that, except that it's meant to be rendered to PDF.
Can you explain why you need browser support for epub?
