To maximize the capture of C02 by planting trees,
1 - plant small areas (a few hundred or even tens, a few thousand m²) instead of non-forested areas (regardless of location, agricultural, urban area, brownfield land etc ...) AND very dense (with species adapted to the environment and varied to optimize the capture in the first years especially)
2- Preserve mature trees in a forest environment, those that no longer extend in crown or height but have the maximum density of foliage and root system and capture all the light and nutrients available during their growth, and store carbon optimally. (these are not young people contrary to an idea still too widespread, but rather those from 100 to 300 years old for species like oak or beech). And the older a tree, the more its genetic diversity increases through the accumulation of mutations (transmissible by seeds). So potentially more likely that interesting mutations will appear and allow some descendants to adapt to new climatic conditions.
3- Use lumber or construction rather than passing entire forests in crematorium ovens (Gardanne) to make electricity (it is not so carbon neutral ...).
4- develop agroforestry which increases the overall yield of carbon storage per hectare, whether for meadows or food crops.
