I want to secure my btc for a long term hold, but I don't know if I feel comfortable with cold storage.
Make a hidden Veracrypt vault on cold computer. Inside the Veracrypt vault save Keepassxc vaults. Store your seeds inside the Keepassxc vaults. For a paper backup, encrypt your seeds using an offline AES256/512 text encryptor/decryptor. Encode the encrypted text using an offline qrcode generator. Print out the qrcode. Test recovery using a dummy wallet. Be sure you can scan and decrypt. Bonus: Laser etch the qrcodes on metal plates. Make a multi-factor recovery vault, in case you forget your passwords. Shimar's secret sharing scheme is a useful tool for making your recovery vault. Never store your seed unencrypted anywhere, ever. Never input your seed on an online computer, ever. Always protect your seeds with something you know (password), something you have (vaults and keyfiles). Do not upload your vault to the cloud. Keep backups in multiple locations. Necessary tools: Cold computer: Any old computer will do. Just physically disable network access.

What are some best practices for securely storing my 12-word seed phrase and how can I recover my funds if I accidentally lose or forget my seed phrase?

Shamir Secret Sharing
If you want to check out the sources yourself before using, of course those are available under GPL at https://github.com/paritytech/banana_split/

What GF should I use when it comes to secret sharing? And why?
Most secret sharing projects use 8-bit values in GF(28) / GF(256), with 0x1B / 29 decimal as the galois polynomial bitpattern. (That's the same one used by AES) The https://github.com/grempe/secrets.js library is widely used. See http://passguardian.com/ -- https://iancoleman.io/shamir/ -- https://bs.parity.io/
