It’s encouraging to see agreements from multiple estimates on the effectiveness of forestry. On clean energy, note that spending a few dollars to lobby the government to in turn spend a lot of money might be a lot more effective (2nd link), perhaps that explains the disparity.
I think your calculation for the cost of promoting plant diets is conceptually mistaken. The amount of lost meat industry revenue is irrelevant. We want to know how much of our money will have to be spent. For that, it’s relatively straightforward to look up the amount of advertising expenses required to reduce meat consumption (Animal Charity Evaluators has done this research).
This in turn makes me suspect that some of your cost estimates for other technologies might have a similar problem, measuring ‘cost’ in some other economic or business sense besides what we really care about. So these calculations are important things to include in the analysis.
Also, the 1800x spread between silvopasture and roofs should considered a significant overestimate due to the optimizer’s curse.
FYI, some prior work (which partially agrees with you):

Also, a bit of press (and research) on trees: https://www.theguardian.com/environment/2019/jul/04/planting-billions-trees-best-tackle-climate-crisis-scientists-canopy-emissions
