Plants don't get there energy from CO2. They get it from sunlight. They do however store extra sunlight energy as sugar (CO2 combined with water). The plants can then modify the sugars (glucose) to make cellulose. to grow taller. The sugars(stored sunlight energy) can also be broken down for energy (say at night time). Similar to what animals and fungi do with sugars/carbohydrates.
Under perfect conditions, I think that all plants have just about the same level of conversion efficiency.
But if it was blackish water, certain plant would be stunted or even die outright while others would be fine.
You might find that in soils with low nitrogen levels legumes do much better, than other plants.
Or with heavy deer pressure or maybe insect xyz, everything is stunted except for plant ABC.
But overall the answer would be legumes family(low mineral) and grass family (low water).
I do however find that grasses and legumes, die back to the "root" very quickly and so very little carbon is actually stored in their body.
All the carbon that they capture is eaten by animals, humans, insects, fungi and quickly turned back into CO2 when we exhale and methane when we fart.
Trees are better because they regularly grow to 40ft sometimes 300ft+ and they live for 40yrs sometimes 2000yrs+
So the carbon that they capture from the air is stored for sometimes until it rots (eaten by fungi) and is turned back to CO2.
My preference would be to see it turned into biochar. Due to the fact that after 50% of the carbon in the "wood" is turned into heat+CO2. the remaining half is not food for animals/fungi/plants. SO that carbon is actually taken out of the atmosphere for millions of years vs for just a season or 50yrs.
Iterations are fine, we don't have to be perfect
