For me, I successfully USB booted the RPi (3B and 3B+) using the following drives
1. 2TB Seagate Barracuda HDD, 2,5"
I haven't found HDD to spin up fast enough, even with the extended timeout set. I'm curious if you ever encountered that issue and if so, how you overcame it.
Mine were old 3.5" internal drives. Both using a USB docking station with its own power supply. A couple times it booted, but usually it would timeout. I had hoped to overcome it simply by powering on the docking station a few seconds prior to the Pi. However, the drive really didn't begin to spin up until the Pi was turned on, so that idea didn't pan out.
I have booted from USB "thumb" drives fine, but I like external HDD for big long-term storage. I have a couple USB-powered WD and Seagate external HDD that I like for that. But I've not tried them yet for Pi booting. I was concerned they'd be too big a power draw, but they do run fine when connected to an already-running Pi. They're readable.
