Why not say non ho potuto parcheggiare (“I couldn’t park”) instead?

Non ho potuto parcheggiare (passato prossimo) simply states you were unable to park. It doesn’t convey that you could have parked but didn’t. Avrei potuto parcheggiare emphasizes that the option existed, but you didn’t take it because the spot was already taken.
