But NoteHead has a duration-log property ready to go:

%%%%
\version "2.22.0"

\layout {
  \override Voice.NoteHead.stencil =
  #(grob-transformer 'stencil
    (lambda (grob orig)
      (grob-interpret-markup grob  #{
        \markup
        \with-dimensions-from \stencil $orig
        \overlay {
          \raise #1.25
          #(number->string
            (ly:grob-property grob 'duration-log))
          \stencil $orig
        }
      #})))
}
{ 1 2 4. 8 }
