I moved from Pandoc+Lua filters to Typst. Having the scripting language integrated is just nicer, though I sometimes miss the separation between data (from Pandoc markdown) and code.
I use it to generate PDF. The last release introduced experimental HTML output which is promising but still immature. Work on EPUB support hasn't started as far as I know but it's on the roadmap, and I guess it will be relatively easy once the ongoing work on HTML and accessibility is done.
