Serious question, what do they have in spades in terms of aircraft? If you were trying to make your attack as impactful as possible, which planes would you deprioritize as targets if you had perfect intel and opportunity?

At about $50m each, that's up to $200m in damage. Tack on the specialized radar, missile systems, and five (?) fighter jets Ukrainians hit in the last few days... just these hits have probably cost the Kremlin well over half a billion dollars in the last week.
