I am installing a 8 foot by 6 foot iron trellis for privacy. What is a good
plant that would cover the trellis relatively quickly and not require a lot
of attention other than watering and some occasional trimming?

Others have mentioned all of the perennials I thought of, but if you
don't mind planting seeds there are lots of annuals that would fit the
bill (if winter privacy is not important). The hyacinth bean vine
(Lablab purpureus) grows fast and lush and sports multiple sprigs of
nicely scented lavender flowers which turn into attractive purple seed
pods. It reseeds freely. Moonflower (Ipomoea alba) is a fast growing
vine similar to morning glory which produces many large white flowers
which open at dusk and smell really good. It attracts hawkmoths and
probably will reseed in your area. Spanish flag (Ipomoea lobata) is
another fast-growing annual vine that produces novel multihued flower
sprigs in abundance and probably would reseed for you. Cup and saucer
vine (Cobea scandens) can climb pretty high but sometimes takes quite a
while before it really takes off and starts blooming.
