I just purchased a quality 18" depth root barrier for a Chinese elm, burch, jacaranda, and Hass Avocado. The garden supply place that I bought the barriers from said I should install them bellow the grade so I can get the barrier as low in the ground as possible. This video that I found online (link attached) claims that barriers need to be installed above grade for aggressive root systems. Do the trees that I have fall into this category? What would you recommend?

It is usually good to leave the top edge above ground level. Generally about 4" to keep mulch and such in place.
I'm not thinking that it would matter much for the plants you mention. They are not plants that put roots above ground, lke with bamboom and such.
Happy ditching.
