Looks daft to me, much work for little gain. Design awards don't always

Is your slab level? In most cases it would be. Water will not run off and
so there is an excellent chance of having a big drainage problem unless the
cracks go right through the concrete to some porous soil. Stunted roots,
plus baked when it's dry, plus drowned when it's wet equals dead plant.

My other idea is to paint the concrete terrazo style looking and use
raised beds with benches and pots and umbrellas and stuff.

That sounds like a much better idea, and could be very lovely.
And a LOT less work! Are you in a not too hot climate?
My area has not been under 90F since July 2, plants would be
really scorched here. (besides you might be sorry some day if
you put all those cracks in your concrete!)
Have fun with your project.
