Wallet Security

I think I’m over obsessing. I have a COLDCARD Q 24 word seed generated from dice rolls Back up on titanium plate, sealed with tamper evident stickers, signed and dated, I’m adding a passphrase now Configured to add ~128 bits of entropy Dedicated to memory No physical backup Now I’m wondering if this is 100% secure or if I should get additional air gapped cold wallets from different manufacturers and do a 2 of 3 multisig wallet and then keep the physical devices and seed backups all in different secure locations.
