That overrides in the main music do not influence \tempo,
\note or \rhythm is intentional. However, \rhythm has more
flexibility than \note because you can just put overrides
inside it, like

\version "2.24.0"

customFlag = {
  \override Score.Flag.stencil = #ly:text-interface::print
  \override Score.Flag.text = \markup {\raise #-0.2 \beam #1.0 #0.05 #0.5 }
}

\score {
  \new Staff {
    \overrideTimeSignatureSettings 4/4 1/8 #'() #'()
    \time 4/4
    \customFlag
    \tempo \markup { Mechanical (\fontsize #-1 \rhythm { \customFlag 8 
} \hspace #-0.6 = 92 )}
    c'8 8 8 8 8 8 8 8
    c'8 8 8 8 8 8 8 8
  }
}


It's also possible to do that globally with

\version "2.24.0"

customFlag = {
  \override Score.Flag.stencil = #ly:text-interface::print
  \override Score.Flag.text = \markup {\raise #-0.2 \beam #1.0 #0.05 #0.5 }
}

\layout {
  \context {
    \Score
    \customFlag
  }
  \context {
    \StandaloneRhythmScore
    \customFlag
  }
}

\score {
  \new Staff {
    \overrideTimeSignatureSettings 4/4 1/8 #'() #'()
    \time 4/4
    \tempo \markup { Mechanical (\fontsize #-1 \rhythm { { 8 } } 
\hspace #-0.6 = 92 )}
    c'8 8 8 8 8 8 8 8
    c'8 8 8 8 8 8 8 8
  }
}


(Note the necessary extra braces in \rhythm { { 8 } }; this quirk has
already been solved, in the unstable version 2.25.0.)

Unfortunately, \tempo internally uses \note, which does not have the
same sort of customizability. You can use tags, though:

\version "2.24.0"

customFlag = {
  \override Score.Flag.stencil = #ly:text-interface::print
  \override Score.Flag.text = \markup {\raise #-0.2 \beam #1.0 #0.05 #0.5 }
}

\layout {
  \context {
    \Score
    \customFlag
  }
  \context {
    \StandaloneRhythmScore
    \customFlag
  }
}

\tagGroup midi,layout

mus =
\new Staff {
  \overrideTimeSignatureSettings 4/4 1/8 #'() #'()
  \time 4/4
  \tag layout \tempo \markup { Mechanical (\fontsize #-1 \rhythm { { 8 
} } \hspace #-0.6 = 92 )}
  \tag midi \tempo 8 = 92
  c'8 8 8 8 8 8 8 8
  c'8 8 8 8 8 8 8 8
}


\score {
  \keepWithTag layout \mus
  \layout { }
}

\score {
  \keepWithTag midi \mus
  \midi { }
}



Best,
