Turning the existing rpi table on the wiki on its side gives us the
following prototype:

  https://wiki.freebsd.org/MarkLinimon/WorkArea16

I'll add more information if people on this list a) think it's useful,
b) will send me the data.  I am too overcommitted to gather it myself,
but I can edit it.

For the hobbyist user, your table is ok.

The professional users (Build custom boards based around a SoC and custom FreeBSD images based probably on stable) are interested in which SoC (bcm2837, AM335x, iMX6...), support for SPI (speed/mode), I2C, UART (Yes still using UARTS), GPIO, ADC, PWM, SD/emmc/flash/... USB, some are also intrested in LCD (16, 24bit, resolution), Touch interface.
If drivers exists for the SoCs watchdog, RTC, DMA and so on.
Of course its nice to have a fully functional eval card from the SoC vendor for example 
http://www.ti.com/tool/tmdsidk574 or http://www.ti.com/tool/tmdsevm572x at the same time the Beagleboard X15 and Beaglebone AI is the same SoC family and its cheaper and still do the job to provide initial development platform before the custom boards are produced.

And the professional users are still looking at the 32bit ARM due to $cost and of course the 32bit is quite cooler than the 64 bit and can be cooled passive without fans when embedded.
Other aspects are how long the SoC vendor "prommise" to produce their SoC family.

Of the RPi family the "most" interesting product are the compute module
https://www.raspberrypi.org/products/compute-module-development-kit-2/

To get more manpower to the whole project i belive its cruciale to attract the businesses to build solutions with the BSD code as the base of their products.
