Does cardboard over the soil with bark chips on top help Florida soil?

help with controling weeds?or do you want to amend the soil?

The short answer is "no". What are you trying to accomplish?

I'm in Oregon but have decomposed granite for soil and a professional landscaper told me to put down cardboard, let it get wet and that would smother the weeds and I could design it the way I wanted. Cover with bark chips, gravel, or ?? Use cinder blocks stacked like bricks to make a raised bed garden, put a row of bricks on top for a finishing touch,. making sure the cardboard is doubled at the bottom of that and fill with soil, plant whatever you want, herbs, veggies, flowers, whatever you wish.

Most sites do not tell you to use cardboard for amending soil,it is strictly mentioned for controlling weeds.

Yes, cardboard is better for controlling weeds. It will disintegrate over a couple years though. Get a soil test through your county agricultural extension office. They are local and will be able to help you best. It is not expensive ($9.00) and will tell you what your soil needs.
