here you can see how I'm using Shamir Secret Sharing, I gave clear instructions on how to use the shares and in what circumstances.

based on their dynamics, I'm feeling pretty good. I know I have some people there that are tech savvy + some that will take good care of their shares and when they should send those to whom.

Implementation is trivial (especially if you find a library) but maybe you can be inspired by my plan https://g3rv4.com/2022/04/a-plan-for-my-secrets

I was wondering, how much do you trust these tools? Cryptography can be extremely tricky to implement. For example, has the tool been checked for side-channel attacks? Has it had any other audits? (On the GitHub page of the library, it says it's no longer maintained)

I trust it enough no solve my DR scenario. If I was targeted by the NSA, I don't expect this to keep me safe.

I don't think SecretSharingDotNet has had any audits, and I'm pretty sure i hasn't been checked for side-channel attacks. I couldn't find anything in GitHub [1] saying it's no longer maintained though.

I'm pretty sure a well founded attacker would be able to hack me, but I think it's orders of magnitude more likely that I'll forget my master password, I'll get stolen, my apartment will catch on fire or I'll just die. Those are the scenarios I'm preparing for.
