It's a Celeste, yes.
Celeste in my area (Atlanta) have either dominant 3-lobe or 5-lobe leaves (or both). Leaves are a poor indicator compared to fruit when it comes to Celeste.
A felt-like or non-shiny skin with pronounced ribs on the fruit, which is about the size of a quarter with a small uniform stem leading to the fruit, void inside the fruit, strawberry to strawberr-red interior.... totally a Celeste. Especially if the skin cracks when ripe.
Some may disagree. I would bet money this is Celeste, or a Celeste variant.
