I'd prefer to trust something like a self-hosted Vaultwarden instance [1] with emergency access [2]. Maybe with redundancy even.
It works as a "dead man's switch". As long as you sign in at least once a month your note will be stay private. Otherwise, your designated recipients will get it in the email.
All the information your write in your note is encrypted using 256-bit AES key. Encryption keys and the data itself are stored in different services. So even if the database is leaked/hacked, the information will not be public.

As any other platform WeExpire could temporarily go down, but it will be always back online before than the minimum inactivity time you can set up in your emergency note (1 day).
If you use this service (or any other of the ones mentioned in the other comments) you'll need to periodically check that they are ok (and that all your details are up to date).
