Yeah, I lived in FL all my life, and texture was always used. Orange peel texture on walls, kitchen and bath ceilings, and popcorn on the rest "back in the day", and "knockdown" texture on the ceilings in the more recent years. Moving to NC, it was a shock to me that all walls and ceilings were smooth finish.
I've gotten used to it, but to be honest, I don't see a difference in holding dust or cobwebs. My last house here in the garage was filthy after a couple of years, and my last home in FL was about the same. Both required an equal amount of work to clean up.
My opinion is that you should do whatever you prefer. If you aren't as good at drywall, it may be beneficial to you to add some texture to hide the imperfections. If you can spend the time and effort, smooth finish works well. Either one will benefit from primer and a couple of coats of paint, and the glossier finishes make it easier to keep clean. (A semi-gloss paint will clean the same whether it is over a smooth or textured wall)
