Jacaranda and Poinciana are both terrible candidates for bonsai indoors/anywhere in the north because they have big compound leaves and long internodes. Any smaller leaf fig will grow easily, and Bougainvillea, Arboricola Schefflera, Tamarind, Portulacaria, Cotoneaster, Boxwood, Elm, Chickasaw Crape Myrtle, and most Azalea & Gardenia that are sold in supermarkets around holidays work well always under lights. Junipers can be trained to never go outdoors, too, BUT that's the secret, always under and close to lights and watered regularly so they never are too wet too long or bone dry. That is very hard to do unless the owner is a very regular, regimented person who never skips part of the schedule. All these should be grown as mame and the same general size so that the lights are all about the same distance above the plants. Using a mirror like a door-mounted dressing mirror size as a table top also helps brighten the immediate zone. Movement of air needs to be continuous, but not so vigorous so as dry too quickly. Close to lights means heat that needs to be moved away. LEDs are much cooler and need to have the proper red/blue ratio, so only buy the more expensive banks designed as grow lights. Small is easier to obtain and to maintain and will give the owner something to do routinely, too, keeping them tidy.
Once they are bug free there is no source for new infestations, but it is necessary to put every new one through a cleaning routine that should include systemic drench like Bayer 3-in-1 Rose Care, hort oil spray & drench, dust with Sevin, and spray with 1 or 2% dish-washing soap like Dawn in water, then rinsed with clear water. Once the herd is pest-free, life is easy. Every new plant is like bringing a whore in, you have no idea what they have around.
Eventually, when you get better with not killing them there are several Cypress species for warm climates that work well, but not as a newbee.
