You can for example use it to run specter-desktop (https://github.com/cryptoadvance/specter-desktop) on top for example, to use your hardware wallet with improved privacy or even mix them together to create multi-sig setups.

Also, the functioning of your hardware wallet isn't dependent on this corporations still existing. There is various free and open source software that lets you manage your hardware wallet, and even combine them to make multi-sig wallets (https://github.com/cryptoadvance/specter-desktop) . This lets you access all information via your own Bitcoin node, no third party system required, fully decentralized.

Take a look at Specter Desktop (https://github.com/cryptoadvance/specter-desktop) , which is a web interface for Bitcoin Core that lets you use basically every hardware wallet directly with your node.

Alternatively you can purchase multiple devices from different manufacturers and create a multisig wallet that requires multiple signatures from multiple devices. Wallet software like Specter-Desktop can help you with this. They also have a DIY signer https://github.com/cryptoadvance/specter-diy

What you can do is to use one or more of this hardware wallets with your own node and a software like specter-desktop (https://github.com/cryptoadvance/specter-desktop) on top. This way you are completely self sufficient.

It is most likely an issue that is solved in the upcoming version of Specter; you might be interested in trying this prerelease, or wait for the official release: https://github.com/cryptoadvance/specter-desktop/releases/tag/v1.13.1-pre1

Look into Seedsigner. It's awesome.

The link didn't seem great, Seedsigner uses a Pi Zero, I have no experience with it but it looks interesting especially for the for the somewhat paranoid.

Seedsigner (BIP85): https://seedsigner.com/ Release 0.6.0 = https://github.com/SeedSigner/seedsigner/releases/

Coldcard is a solid, bitcoin only commercial option. If you don't mind a little DIY then Krux or seedsigner might be a good choice too. You can also make your own with an old laptop. Remove the WiFi functionality (rip out the board or antenna) and upload Linux. Install a wallet on there like electrum or sparrow (transfer it over via usb) and you have an airgapped wallet.

For Seedsigner it's capable of deriving P2SH and P2WPKH adresses. But there's a github issue open, that could bring your requested feature. Let's see...
