Having suffered also from parentheses that didn't match the size
of the parenthesized object (for me, parenthesized chordmode
symbols), and having seen no follow-up to this thread, I am
pleased to have found this gem in the docs today.

I'm sure it's been there all along, but thank you, documentation team!

\relative c' {
  c2-\parenthesize ->
  \override ParenthesesItem #'padding = #0.1
  \override ParenthesesItem #'font-size = #-4  % <-- that one!
  <d \parenthesize f a>2
}

or

\chordmode {
  \override ParenthesesItem #'font-size = #1
  \parenthesize a1:m7
}
