I know this is going to sound like BS, but I have to see a place and get the energy of it in order to know what to plant. However, I did a search to see if I could find you a website with native plants to your area and I found a great site! You punch in on the drop down menu exactly what you'd like, color, bloom time, size, type (vine, tree, shrub etc.) and it brings up the plants native to where you live.
I always recommend native plants because they need nothing once they are established. Now and again there may be some species which need more water or added fertilizer, but not likely once they are established. Your soil sounds really good. My soil is very good also. It is an old homestead for a huge farm and ranch. When they dug the pool the soil was beautiful 4 feet down, then the white caliche was there! But that is definitely deep enough for any plant on earth.
That said, one vine which is native and will attract hummingbirds is Crossvine. I also like Trumpet Vine. It's always good to mix things in like shrubs, herbs, vines, trees on a fence line. You can add every year using seeds. Plants can get expensive, but a tip is that you should always buy the smallest version. So if you see a perennial like Lavender (for example), it is best to buy it with no flower and in a 4" pot. By the time a larger plant gets settled, the smaller one has already established and will soon be the same size as the more expensive plant. Even when buying annual flowers you should always choose tight, compact plants, stiff stems not flopping over and no flowers. If there are flowers on the annuals, trust me and cut them off before planting them. In faster time it will settle and have the next amazing flush of flowers. Perennials should be dead headed after blooms are finished and you may squeak out a second smaller flush if you also give a shot of fertilizer to your perennials after they bloom and you remove the dead blossom.

So, so much. I swear eventually I will have written a book. If I pull all the articles and essays I've had published together I could probably have a respectable manual for gardening.
LA can write the book on how to grow cannabis and I can have a section on how to keep the rest of the place looking pretty!
