at intervals of 3,750 miles (severe) or 7,500 (normal).

I personally don't feel comfortable running a conventional oil to 7500 miles. I'm going to be dumping the FF soon on my '18 and will use synthetic for the life of the car. With rebates, syn is cheaper than dino anyway.
Take a look at the severe service schedule in the manual. If you drive in stop and go traffic daily, I would go with the severe service schedule while under warranty. Hyundai is notorious for picking the fly poop out of the pepper when it comes to warranty requirements being met.
