I've set up Bitwarden granting time-delayed emergency access to a couple of family members.

I've also left a thumb drive with a Bitwarden export and printed paper in a safe place for my family, describing how to access everything important.

I trust my family not to abuse that, but if I was less trusting I'd look at Samir's Secret Sharing to ensure family members had to collaborate to retrieve my sensitive info. Or leave the data with a lawyer.

I made sure to pass on my 2FA secrets too.
