You do:
\wordwrap {"a very very very very very very very very long row 3"}
i.e. wordwrap gets a markup-list with exactly one entry, a line-break
will never happen this way.

Either use wordwrap-string like:
  \override #'(line-width . 12)
    "a very very very very very very very very very very very very long text 3"

Or wardwrap with a suitable markuplist:
  \override #'(line-width . 12)
     a very very very very very very very very very very very very long text 3

Has nothing to do with the table-markup-list-command but with \column
and similar markup-commands.
  \column {
    \box \column { a b }
    \box \column { a b }

This minimal is fixable with:
  \override #'(baseline-skip . 6)
  \column {
    \box \override #'(baseline-skip . 3) \column { a b }
    \box \override #'(baseline-skip . 3) \column { a b }

Though I've currently no good idea how to do so in \table

No, at least I know none.

Here again I'm sorry being of no help.

Though this behaviour bugs me as well, here a less complex example:

#(set-default-paper-size "a7")

mrkpl =
  \justified-lines {
    Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod
    tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam,

    turpis et commodo pharetra, est eros bibendum elit, nec luctus magna felis

    tellus et risus vulputate vehicula. Donec lobortis risus a elit. Etiam

    commodo eget, consequat quis, neque. Aliquam faucibus, elit ut dictum

    Cras mollis scelerisque nunc. Nullam arcu. Aliquam consequat. Curabitur
    augue lorem, dapibus quis, laoreet et, pretium ac, nisi. Aenean magna nisl,
    mollis quis, molestie eu, feugiat in, orci. In hac habitasse platea


\paper {
  top-markup-spacing =
   #'((padding . 15)
      (minimum-distance . 15)
      (basic-distance . 15))
  %annotate-spacing = ##t
  %ragged-last-bottom = ##f

Looks like the provided values for top-markup-spacing are not
called/used again before the markuplist ended, even if distributed
over several pages.
