I think a note with the master password or key to your password manager in a fireproof safe or safety deposit box (depending on the need for immediate access prior to probate).
Having many passwords means the list needs to be updated constantly. Having the master means whenever you change that one.
Source: dealt with this for my dad when mom passed. Though hers was a spread sheet with handwritten updates. Most of them even worked, but she was a very fastidious person (are you?).
I would ideally do it periodically, but with the full list. The risk with just storing the master password is that underlaying password store gets lost or broken (e.g. bitwarden goes bankrupt, PC storing keepassx dies etc).
The churn aspect is a problem though, its not perfect.
