Forests do net sequester carbon. But if you want to really sock away the carbon you harvest the trees and pyrolize it. It will give you energy (heat) you can use and elemental carbon (biochar). You could bury that a few feet under or innoculate it with microorganisms and work it into fields. Carbon in that form will sit in the soil for hundreds of years. Thousands or millions if you bury it.
I mean technically we already do this: renewable plantation timber is a widespread operation (also why I get kind of annoyed at YouTubers talking about how great the timber is in old homes - yes it's great because it was logged from 50 year old old growth forests and now they're all gone because we cut them down).
You can just buy engineered wood products that are much stronger than any old growth lumber. My family lake house built in 1970 has three gluelam trusss beams that support the roof. There are even better engineered wood products available these days.

And what is the scale that global climate change works on?
Trees do jack shit for carbon on the scale that is important.
