I had similar experiences. Do you have any USB devices attached?
One thing to watch for is any mounting of USB drives. I also had problems with certain cables connecting USB drives to the Pi but when I placed them on a powered hub they were fine (not slow to mount). As a reference, running devuan I had no issues.

If you have USB drives attached, try this: place hw.usb.no_boot_wait="1" in /boot/loader.conf

I've never tried this. Is this now possible because it's a Tier 1 architecture?
Would not memory be a constraint here? You definitely wouldn't want to be using tmpfs system.

And usually they start exhibiting write issues beforehand if they're going to fail.

Have you looked in /var/log/messages to see if there's any help there?
