I once tried to follow an idea of David Kastrup's (see 
https://lists.gnu.org/archive/html/lilypond-user/2021-03/msg00031.html) 
to create a \rhythm markup function. I never got around to finishing it 
(the hard part is to make "the right things" configurable I think), but 
it seems to be usable at the moment:

#(define-markup-command (rhythm layout props content) (ly:music?)
   #:properties ((time #f))
   (interpret-markup layout props #{
     \markup {
       \score {
         \new RhythmicStaff \with {
           \override StaffSymbol.line-count = 0
           \override Rest.staff-position = 2
           \override BarLine.bar-extent = #'(-0.5 . 2)
           \override TimeSignature.Y-offset = 0.5
           #(if (not time)
                #{ \with {
                  \remove Time_signature_engraver
                } #})

         }
         {
           #(if time #{ \time $time #})
           #content
         }
         \layout {
           indent = 0
           #(layout-set-staff-size 12)
         }
       }
                     } #}))

Possible examples:

\markup { Als Triolen ( \rhythm { \tuplet 3/2 4 { r4 8 4 8 } } ) 
auszuführen. }
\markup { Tempo comodo, ma \italic shuffle (\rhythm { 8[ 8] } = \rhythm 
{ \tuplet 3/2 { 4 8 } } ). }
\markup { \override #'(time . (3 . 4)) \rhythm { \time 3/4 4 4 4 4 4 4 4 } }

In your case, it's simply

\relative c' {
  c4
  f^\markup \center-align \italic \small { (v. 6 \rhythm { 8[ 8] }) }
  f a
}
