Laura,
I'm no expert on ponding, but I live in FL, and I have a little pond right next to my house in a very restricted area, so I can address some problems we share that others might not see.
Your house appears to be new, so I don't know how much experience you have with FL gardening. For the benefit of those who have no experience in this, I will pretend you haven't done much gardening here until you tell me otherwise.
Your pond will lead to a massive influx of Cuban tree frogs. If you don't know them, these are usually white or gray and have enormous suction cups on their toes. They are cute when they are little. Supposedly they get to be as much as 5" long. I saw one that I am sure was over 6" long. It was not cute. They spend the night at your pond croaking loudly and producing vast quantities of stinky eggs. During the day, they hide in any crevice or hollow they can find on your house. They eat lots of bugs, and unfortunately, they also eat native frogs. Then they poop all over the side of your house -- big dark brown splashes that will stain if you don't wash them off right away. Unlike any other frogs I know, they will also jump on you (and stick on with those big suction cups) and will come in the house if they can. We finally decided that we had to catch and euthanize our plague of Cuban frogs, and life has been better.
I assume you have sand in Naples since most of Florida is sand. If so, you will need to reinforce the sides of your pond with cement blocks. I learned this the hard way. I had finished digging my pond and put in the liner when we had a nice FL rainstorm. It collapsed into a mass of mud. The only sides remaining were where I had made plant shelves with cement blocks. So I emptied the mess, redug it and put cement blocks all the way around. I just set them in place -- no mortar -- and they work fine. It's really important to make sure the edges of your pond are substantially higher than the ground around them. I didn't think of that, so every rainstorm washes silt into the pond and any heavy rain makes it overflow. When I rebuild this winter, the pond level will be six inches above the ground. If you are going to have plant shelves, make sure they are wide enough for large pots. Mine are a cement block wide, and that isn't enough. I'm going to eliminate the plant shelves when I rebuild. I'm looking at some of those black plastic stacking shelves for plant shelves. They would also provide a shaded hiding place for the fish under the plants.
Make sure you have enough space to work around your pond. If you are always crowded, maintenance isn't easy and tends to get neglected. I now have my pond completely surrounded by either pavers or a gravel path with stepping stones. I have lots of vegetation in pots.
I've been thinking about how to make a filter look good, and have some ideas, but this post is too long already.
