Hey there, JENast!
Congratulations on your new iPhone 11 Pro Max! If I understand your post, you'd like to know what cable to use with iTunes on your Windows PC in order to sync your music. I'm happy to help!
It's recommended that you utilize the Lighting-to-USB cable that came with your iPhone 11 Pro Max. In lieu of that, you can use another Apple-certified Lightning-to-USB cable (you'll know it's Apple-certified because it will say either "Made for iOS" or "MFi" on the packaging). Then you can use the steps in Use iTunes to sync your iPhone, iPad, or iPod with your computer - Apple Support to sync.
You also have a few wireless syncing options available. For example, you can sync directly from iTunes to your device if both your computer and iPhone are on the same Wi-Fi network, which is described in the above article. You can also subscribe to iTunes Match: Subscribe to iTunes Match - Apple Support or Apple Music: Join Apple Music on your iPhone, iPad, iPod touch, Mac, or PC - Apple Support.
Happy listening!
