This has been studied pretty extensively, for example: https://www.fs.usda.gov/treesearch/pubs/38598

Some key points are:

1. Forests reach their maximum level of carbon sequestration after around 70 years. After this point, they are no longer a net carbon sink.

2. If you periodically cut down the trees, turn the wood into long-lived products (like buildings), and then replant, you can sequester more carbon.

3. Exactly how much more depends on assumptions about the length of the useful life of a building and what is done with the wood after the building reaches the end of its useful life.

4. If you're looking at net carbon emissions, you also need to consider substitution -- by using wood in a building, you're decreasing the need for other building materials like concrete and steel, which emit a lot of CO2 in their production. They model various scenarios on the paper.
