Nice, bike. Congrats!
I still encourage you to put on the 28 mm GP 5000 tires. At a speed of 20 MPH, you would save around 20 W of power running GP 5000 S TR versus the Bontrager R3s (if that's what came with your bike). You'd definitely notice the better rolling resistance.
But if you run those Bontragers a bit, get a feel for them and note your ride speeds, and then get some GP 5000s and you'll see the difference in your data (if you measure things like that).
