The P1S is so powerful! You're gonna have so much fun with it, there's endless stuff you can create. When you start digging in the rabbit hole goes deeeep.

Like the programs alone, I still use Bambu for my slicer, but I primarily make functional things so I make models with measurements in Fusion. I use Illustrator a LOT for vector work, and if I wasn't so indoctrinated into the Cult of Adobe I'd absolutely be using something like Inkscape.

On the other hand, for art and figures there's Blender/zBrush for organic shapes and sculpted stuff. And that's just scratching the surface, it all really depends on what kind of stuff you want to create!
