I 100% mostly do this in Long Beach, CA as well.

During peak traffic hours you focus on staying by the higher-end restaurants, delivering to the wealthier neighborhoods and family suburbs, plus being professional and trying to stand out a bit from the average Postmate.

Especially during peak traffic hours + Postmates lunch/dinner demand that's the best gameplan to have. Definetly have to be picky about which orders to take during 6:00 traffic to keep your sanity and avoid certain intersections. It's usually only worthwhile to do farther deliveries during traffic time if the order is big and you're hoping for tip. Or if it's to a destination you want to do pickups from or end at.
