One day I'll sit down and just go through them all to fix them.
I had a spate of going through and putting in 2FA on everything 1Password indicated could have it.
Then, I had another spate of changing all my passwords on accounts I still had in my defunct LastPass. (I switched from LastPass to 1Password before the big breach.)
You should try going through the list and deleting accounts you never use anymore. That one's always fun because many companies try to hide the delete account button or simply don't have one
There are services that do this by using GDPR rights. I think they scan email for "Welcome" emails, then automate the account deletion as far as possible.
We get about 5 emails a year at work through these services, as we don't have a "delete account" button.
