It doesn't produce invalid html, it produce html 4.01:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

Which is different to xhtml which would get with the xhtml option

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

bibtex is an application and biblatex a package.

The transition is more

bibtex + natbib or bibtex + jurabib or bibtex + some bib-style ->
bibtex + biblatex or biber + biblatex.

these are formats for very different purposes. pdf is a page
description format, while in ebook/web-formats text can be easily
refloated.

PNG is a bitmap format, SVG a vector format. How would convert a
foto to a vector format?

I will certainly never use LyX, and I don't any TeX/LaTeX/context
expert who considers such a step.
