We went in 2022. I recommend two days in Athens at the most. It has a compact area of main sights, while the rest of the city is run down.
We stayed another few days at a resort focused on locals at the end of the Sounio Penninsula. It was nice and not crowded or expensive.
Did a long day trip to Delphi, which was highly worthwhile.
We did not go to Santorini as we heard it is overrun with tourists. I have heard there are very nice, less crowded islands, but those were not on our agenda for that trip.
