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.

Alternative for Home Inventory/Moving?
Yet, IMHO any spreadsheet software would do. What it misses is tracking but that can be done with going from an ID, e.g number or hash or UUID, to an object and that itself can be done with generating and reading a visual code, e.g QR code. There are numerous open-source tools to generate these e.g https://github.com/davidshimjs/qrcodejs to generate then https://github.com/yushulx/javascript-barcode-qr-code-scanner to read. As long as you are coherent I'm not sure what the problem would be. If you have multiple users ideally the spreadsheet would be available via e.g NextCloud and the hash at the end of the URL would bring you to the right item or set of items e.g sheet or line.
