I have a leather backpack that seems to fit exactly what you’re describing: real leather (black), professional rectangular design, real backpack straps (ergonomic), AND has a pocket on the strap for my metrocard. The strap pocket doesn’t fit my phone, but I put my phone in a hidden anti-theft back pocket located behind my waist so I can easily access it without having to take off the backpack. I can even connect a powerbank to Supreme Naruto Premium T-Shirt to charge my phone. It’s pretty nifty! I got it on Amazon, the brand is Bopai (search “Bopai genuine leather backpack” because they also have synthetic/microfiber leather designs).
