After dd'ing:
FreeBSD-13.1-STABLE-arm64-aarch64-RPI-20221014-56533712694-252734.img
to the USB3 media attempting to boot from the media consistently
got (note the uhub_reattach_port USB_ERR_TIMEOUT lines):

Mounting from ufs:/dev/ufs/rootfs failed with error 19.
Loader variables:
vfs.root.mountfrom=3Dufs:/dev/ufs/rootfs
vfs.root.mountfrom.options=3Drw
Manual root filesystem specification:
<fstype>:<device> [options]
Mount <device> using filesystem <fstype>
and with the specified (optional) option list.
eg. ufs:/dev/da0s1a
zfs:zroot/ROOT/default

(which is equivalent to: mount -t cd9660 -o ro /dev/cd0 /)

So I updated config.txt to (shown from after a
successful boot):
# more /boot/msdos/config.txt=20
[all]
arm_64bit=3D1
dtparam=3Daudio=3Don,i2c_arm=3Don,spi=3Don
dtoverlay=3Dmmc
dtoverlay=3Ddisable-bt
device_tree_address=3D0x4000
kernel=3Du-boot.bin
[pi4]
#hdmi_safe=3D1
armstub=3Darmstub8-gic.bin
#
# Local addition that avoids USB3 SSD boot failures that look like:
# uhub_reattach_port: port ? reset failed, error=3DUSB_ERR_TIMEOUT
# uhub_reattach_port: device problem (USB_ERR_TIMEOUT), disabling port =
?
initial_turbo=3D60
That was in order to boot from USB3, no microsd card
involved. I've not tried to find an approximately-minimal
initial_turbo value. force_turbo=3D1 likely would also work,
as would other forms of clock rate controls in config.txt .
It appears that FreeBSD is sensitive to variations in the
clock rates during booting but the RPi* firmware can (and
does) vary relevant clock rates unless it is told not to in
some way (initial_turbo use here, there are other ways).
Something is needed to avoid timing out too soon.
Note: The media is not my USB3 media that requires the likes
of usb_pgood_delay for U-Boot in order for U-Boot to find the
device. An unmodified/default u-boot.bin works with the media
just fine. Only the later FreeBSD activity has a problem.
For reference, from the successful boot after the change:
