2.5 year old boy taking an hour to fall asleep at bedtime

My son is a good sleeper and napper. He falls asleep in 10 minutes for his nap and I have to wake him from it every day around 2 hours. But the past few months it has taken him a long time to fall asleep at bedtime, around an hour. Ive slowly brought him down from 2.5 hour naps and 4.75 hour wake windows before bed, to today he had a 1.75 hour nap and a 5.25 hour wake window. He took over 90 minutes to fall asleep for bedtime. Idk what else to try at this point. His environment is spot on and doesn’t get screen time in evenings at all. Eats well too. Bedtime is between 7-8.

What is/was your 2.5 year olds sleep schedule like?
