About the letter delivery system, who is responsible for that? If it’s a company, instead of requiring an heir email, it could use a login system, like a digital vault, where the wallet descriptor is stored. The letter would contain the login instructions, and the person in possession of it would have to prove they are a valid heir from a list left by the owner. This approach solves the issue of email technological obsolescence and centralizes the process.
Regarding the cryptosteel, if it contains the seed, all of this is just extra layers—whoever has the seed can access the wallet and transfer the funds wherever they want, without cooldowns or additional verifications.
It’s almost like a bank, which is why I don’t really like the idea, but I’m here to brainstorm, not to judge lol.
Meanwhile, I’m thinking of a more secure and personal model. Since we’re talking about inheritance, it assumes you have direct contact with the person. I also believe they should at least understand what it is because otherwise, the chances of them messing up or simply cashing out into fiat are high. In other words, they need to deserve it.

Not in this case. The seed given to the heir is actually one seed in a 1-of-2 multisig (this is why they need the descriptor--whatever wallet software they use to recover needs to be able to know how to find the coins), but it's a 1-of-2 where the primary key (held by you) can always spend and the heir's key (stored with this letter) can only spend coins if the primary key isn't used for a prespecified length of time. This is enforced by Bitcoin script at the consensus level, so not trusting a third party.
The advantage to this is exactly what you are getting at: an executor or your heir won't be able to spend your funds until you want them to (or stop using your key) even if have access to the seed/hardware signer/letter.
they should at least understand what it is
You are spot on. This is a really important point. At least with current pop understanding of Bitcoin, an heir who has no real idea about it may be very casual in their approach to recover (or just ignore it).
