Jacarandah are lovely, but can be very messy. Figs more so, they drop prolific amounts of seed like dust. Both add a lot to the treescape but I'm struggling they deprecated so many fine native trees. Planting exotics does far less for wildlife.
But yes, Jacarandah and figs are lovely. They do both shed large limbs and get brittle. Not entirely safe in stormy weather.
(Australian experience. Native figs abound here, so I'm applying their foreigner status to California only)
I'm amused by this story

which suggests that people who don't like non-native species have been traveling to your region and bringing back pests that attack Eucalyptus.
That's a very bad idea. They're right to be concerned. Over here we do (mostly) reflect on cane toads which are still a problem but perhaps less than feared?, but it was never funny, and nor are fire ants or varroa mite. Fire ants could wreak havoc on enjoyment of the outside, and the wildlife. Varroa is mainly a problem to an introduced species admittedly (native bees are not affected) but replacement pollinators at scale will take time.
Dung beetles and catoblastus moth were carefully worked through, took decades of work to decide to release.
So back in Cali, bringing the eucalypt in the first place was the root cause.
