Welcome to ATP, Barbie! I hope you enjoy gardening in Mississippi!
Mostly flowers or mostly vegetables?
>> What type of soil should I use?
I think that we all grow in whatever soil we have - except that we spend the rest of our lives improving it.
If you're so close to the beach that you have sandy soil, compost will help it hold water and nutrients. Mulch will help it hold water and keep soil cooler in summer and warmer in the fall.
If you have clayey soil, compost will help it breath and drain better. LOTS of compost will help more. Not everyone agrees, but I think that it is SO hard to get ENOUGH compost into clay that you also benefit from adding "gritty stuff" to the clay: sand, coarse sand, grit, bark fibers, bark shreds and bark chunks.
Very often it helps to pile up a
deeper layer of whatever topsoil you have, into raised beds or even just raised mounds or rows, if that doesn't make watering too hard. Scrape the topsoil off any walkways and add that to the beds. Add lots of compost to the raised beds.
RBs are a way to grow more plants in less space, and protect the soil structure from compaction.
If you buy truckloads or bags of topsoil or "garden soil", add them to raised beds. Store-bought soil is so expensive that it is well worth building raised beds to get the most advantage form what you've paid for. And double-beware what kind of soil you get. I know that the pile I looked at in the "dirt-yard" looked MUCH less clayey then the soil they delivered!
And you might pay $35 per cubic yard for compost. That can range anywhere in quality from "cheap sawdust" to a fully-composted, aged, rich, pure manure product that a veteran gardener would sniff appreciatively for its "bouquet".
I wonder which regional forum that would be?
