If you will stop and look at any of the water features at any of the street corners in TV, you will see they use sand filters. Cleaning a sand filter only requires you to backflush the filter. That's it. It's a simple process. Also, Zeobrite filter media can be used as a replacement for sand in the filter and provides superior water clarity. The sand filter may cost more upfront, but will save time and money over the long run. Determine the size needed for your pool and then go up a size. A little bigger is better IMHO.

I'm not in Florida yet, in Massachusetts. I was skeptical of my cartridge filter when I bought my pool. But it lasted 4 seasons and honestly didn't need to be replaced this year, but I got lazy. I've only had to hose it out about 2X per season. For a pool in a birdcage, without much debris I can't imagine it being worse.
On our pool install, before landscaping drainage was done, we had an epic storm and pool filled with mud. That really taxed the cartridge, but a wash with the pressure washer (carefully) made it as good as new. Anyhow I have nothing against sand filters. The work pretty well.
I'd stay away from DE filters. Had that before and every backwash needs more diatomaceous earth, cleaning them is a nightmare. They do filter the best, but not worth the work.
