Looks like you got one of everything! Congratulations! You’re off to a lightning-fast jumpstart!
Three things to consider when planting are sun tolerance, individual water needs, and mature frond lengths for crowding. Try to get your sun lovers and drought tolerant palms out in the open, blasted by sun, away from the water and shade lovers. Then group your water lovers in the wet areas so they can get blasted with irrigation without rotting anyone else out.
Each spot in the yard has certain characteristics that might favor certain plants, and you can tailor your irrigation and bed amendments once you’ve got the sun spots picked out. Pseudophoenix Sargentii will like to be blasted by open sun, in alkaline soil, and will need to dry out. Satakentia will like to be watered every day to every other day, and might appreciate a little shade break at times. Chambeyronia macrocarpa will fry and die in full open Florida sun, but prosper in a moist shady spot when younger.
Not sure about cold protection in 10a, but others can comment on that.
What direction does the front of your lot face?
When I first moved into my current house, I came from a condo, so we needed a lot of stuff for the inside. Some people advised taking it slow, as you don’t know what you’ll need or how things will exactly fit and flow, until you’ve lived there for a year or so. Since it was just before COVID hit, we took it slow on furnishings and arrangements…. by necessity, at the time. It worked out well.
Same can be said about some of the outside plantings. You’ll get to know the yard, the sun movements during the year, the soil and moisture variations from spot to spot, etc…. Especially if you do your own yard maintenance…. You’ll know every blade of grass, and will notice things very early if there is a problem.
Doing the understory, shrubs, and ground cover is just as fun as palms. Crotons, Ti, Philodendrons, and bromeliads can give you some color accents, leaf variations, and pizazz, but each type will need the same considerations mentioned above. Even boulders and borders can add a lot to the look. And not everyone will survive long term. Things will grow big and fast. Bigger and faster than you anticipated. Things will look a lot different in 2 years.
Great place and house though. You’ve reached the fun stage. Even small plants will fill in quick in zone 10+. Crotons and bromeliads can be more addicting than palms
