As a new pilot I have a question about upgrading the ST16 with the kit that provides a second antenna and the flat wi-fi antenna to the standard controller. They aren't much money $40, so that is not the issue---The issue is---is it worth doing? Thanks.
ST16 question

I did it to my back up ST16 & H480. You probably won't notice any difference unless flying BVLOS, but it was fun to open up the ST16 and do the mod anyway.

Put the second 2.4GHz Antenna from inside to outside makes not much sense. The difference is marginal but the risk to put antennas in wrong direction is high. The best effect is when the two 2.4GHz antennas have an angle of 90° to each other. With the horizontal antenna inside and the rod antenna outside this is given by default (intuitive). But if both are outside the default is to have both in the same direction - wrong. It is then in your rsponsibility to do it right and this is not intuitive.
But the patch antenna for the 5GHz video downlink makes sense. Good to have both. The mushroom is an omnidirectional antenna. Good conditions around you, no matter where the bird is but lower range.
The patch antenna is more unidirectional which leads to more range in this direction. But you can lose the signal if you do not point the antenna to the bird.
If you can buy the patch antenna only (YUNST16109) you can use the optimal antenna for your current task.

Is that why I saw in the German H3 demo video that the 2 stick antenna were angled away from each other at, you guessed it, 90-deg?

Yes, that's the way you should do. Same as the antennas at receiver side:
One of both antennas has always a good signal, no matter where the transmitter is. Or both antennas have a fair signal. Hoever this 90° rule avoids that both antennas are pointed to each other with minimum range.
See radiation pattern of the different kinds of antenna:
