As a general rule, the links which are hard to get, in most cases, offer the most value. But there are different kinds of value. For example, editorial links (huffingtonpost) or other bigger links (wikipedia) are really good links to have but you don't get a bang for your buck in terms of SEO power. However, with these links you establish authority and legitimacy since only a site that is worth anything will acquire those naturally.
Then there are links from sites that are not as well known but are big in their niche. Whatever big cannabis sites operate in your niche are good targets. You will have to spend money, but not as much as the previous category. These links will deliver SEO value and also legitimacy value in your niche.
Ultimately, you want links from domains that themselves have a strong backlink profile. For example, a strong site that sells candy can give you a link if you have a page that talks about weed gummies. A vaping site could link to you in a similar fashion. You have to get creative and be strategic with your targets. Don't worry about getting lower quality links, those will come automatically with time. What you want to focus on is HQ Guest posts and niche edits because these make the most sense to acquire in terms of $ and SEO power.
Other HQ links include HARO links, as well as edu/gov links (if you can somehow get these, again very hard to get and come naturally NOT OFTEN).
Don't fall for link providers here with silly power ranger packages, it is all junk. If someone is selling you 100 links for $100, it is junk. You need to learn to vet targets yourself. Any link that is on a public platform without moderation is mostly junk.
PBNs work well, don't rely on them completely but you can incorporate them into your strategy. The only PBNs worth your time are monthly rentals, one time payment PBN links will die a slow/fast death depending on the provider since they have no incentive to renew the domain once it is filled with junk articles linking out to niche sites.
Poor link building can ruin your site, aim for quality not quantity, and stay away from public platforms as well as xmen spiderman marvel avengers, just like the real world, the SEO world don't have no super heroes
