You list 13.0-RELEASE 's image instead of 13.1-RELEASE 's image:

http://ftp3.freebsd.org/pub/FreeBSD/releases/ISO-IMAGES/13.1/FreeBSD-13.1-RELEASE-arm-armv7-GENERICSD.img.xz

(I've no clue if it makes a difference.)

pkg install sysutils/u-boot-beaglebone

only puts things in the likes of:

/usr/local/share/u-boot/u-boot-beaglebone/

/usr/local/share/u-boot/u-boot-beaglebone/ probably ended up
with a README or some such file name for the content shown
below.

# more /usr/ports/sysutils/u-boot-beaglebone/pkg-descr 
U-Boot loader for BeagleBone and BeagleBone Black.

To install this bootloader, copy the files MLO and bb-uboot.img to the FAT
partition on an SD card or the eMMC.  Normally this is partition 1, but
different partitions can be set with U-Boot environment variables.

This version is patched so that:
 * API features are enabled.
 * A boot.scr (U-Boot scripts ) that loads ubldr.bin and execute it is included

For information about running FreeBSD on BeagleBone or BeagleBone Black, see
https://wiki.freebsd.org/FreeBSD/arm/BeagleBone



You were not explicit. Did you do as described with MLO
and bb-uboot.img ?

Note: I've no experience with any BeagleBone variant.
My comments are rather generic.
