If you can undo the paint on the stone, it would be a huge improvement. You should paint the house a color that allows for white trim. Presently, all the white on the windows fights with the thin, yellow trim.

I'd remove the fence thing at the entry. It does nothing for curb appeal, I doubt it's useful. You have a lot of opportunity for improved curb appeal with landscaping. I'd remove the planter on the right corner and put in a small tree that will be taller than your house. That will soften the boxy lines. You want it slightly forward and far enough away that the mature size won't be a problem. I'd put a small palm in the semicircle garden. I'm no expert on what grows in your zone, but Elephant ears and Canna will bring an instant tropical vibe. They both come with plain green leaves, and can be bought at any nursery as a corm or tuber.

Look up landscaping in Search Houzz. Pick your metro area from the drop-down menu at the top and choose photos. Here's one from Orlando (I guessed where you are). Not the most inspired, but certainly a decent model to copy if you want a plan

The previous owners should never be allowed near a paint store or to make any design decisions, which they seemed to make after consuming too many cocktails!

If the stone is just a veneer, I would get a quote to remove it and replace with stucco.

South FL is one of the few areas where it is relatively easy to "upgrade" the look of a house with just landscaping. Search Houzz photos for "Florida landscaping" and you'll get lots of ideas.

Excellent post by Sigrid. IMO, that gray on your stone is so bad. You could repaint in a more natural color (natural being whatever color stones in the ground naturally appear in your area). Ditto on demolition of the mini fence.

I’d keep the bed in front of your house in some fashion, but those landscape blocks set on top of the ground need to go. Maybe plant something with a vertical growth habit on the right side of the bed, or instead reduce the bed size and set a small tree in the yard towards that small window. Or do away with the existing bed completely. It feels forced, and the lamppost (?) is teeny tiny.

You can use pretty planters in that cement area and use Bromelia type plants that love the heat/sun and don't need much water.

Here are mine in my Lanai. I only water once per week year round.

An Areca palm can also do great in a large planter.

The Bromelia on the left was only one plant when I bought it. There are around 10 plants in there now, which I need to pull out and transplant ... but it does have serrated edges so a bit harder to handle.

I doubt that the painted stone can be undone. It It’s a very labor intensive process and not always successful . The house would look much better all one color except for the trim. I would get a new landscape & hardscape plan that can be done in stages if needed.

The colors are a bit shocking at first but after a few seconds is quite pleasing, esp. for a tropical climate.

But since you like neutral, sandblast the stone and paint the house a golden tan from the stone. The color of the lower brick of the front wall.

A modern light post. Modern porch light. Perhaps a Coral color front door with modern glass panels.

Stay with the color of the painted stone for the body of the house. . Go darker than the painted stone for the front door.

And, landscape!
