Arf, I'm still struggling :
dals = \tweak DynamicText.self-alignment-X #LEFT

#{ \markup \normal-text
\center-column {

\dir-column { "smol" "Very very very tol" }
medium }

I also want to center horizontally (here, the first and second line are
left-aligned, and the third is centered).

Ah, you will need to use \center-align on each element:

%%%%
\markup {
  \column {
    \override #`(direction . ,UP)
    \dir-column {
      \center-align \line { d e }
      \center-align \line { a b c }
    }
    \center-align \line { f g h }
  }
}
%%%%

Note that by doing this, you don't need to use \center-column 
specifically.

If you are using this pattern frequently enough, you could wrap it all 
up in a new markup command:

%%%%
\version "2.20.0"

#(define-markup-command
  (centered-three-lines layout props arg1 arg2 arg3)
  (markup? markup? markup?)
  (interpret-markup layout props #{
    \markup \column {
      \override #`(direction . ,UP)
      \dir-column {
        \center-align #arg2
        \center-align #arg1
      }
      \center-align #arg3
    } #}))

\markup \centered-three-lines
  \line { a b c }
  \line { d e }
  \line { f g h }
%%%%
