Great note SLCW, I feel that my Bitcoin is safer in cold storage as long as I stamp my seedphrase in a SAFU NINJA backup. I bought the stamping tools, stainless steel washers, bolts and nuts from local stores using fiat; having these tools organized in a small tool box, will be useful on the long-run leaving NO digital trail behind, (i.e. laser stencils, sticker vinyls, CNC files, etc.). Coinos allows me to manage (import/export) my seedphrase; transactions fees to/from seedphrase only cost USD$1 but you must have at least 4678 sats for any transaction, which for me is fairly balanced considering that if you want to use Sats for Zaps they still remain easily available on your Coinos lighting wallet - while your bulk Bitcoin is safe in cold storage. Coinos also gives you a live preview of your seedphrase balance in any currency as well as transaction history. Although not every wallet out there offers the same functionalities, seedphrase management is perhaps the most strategic feature for users wanting to save for future investments.
