Thank you for the advise and the understanding.
Fortunately, I was able to regain access to the important accounts (Utilities, Rent Portal, Student Loan Servicer, Phone Carrier, etc.) because I keep the email receipts after making payments.
Got a few aliases from the sender/recipient details… Since I’m only logged out of the password manager, password reset requests still forward to my main inbox. Also, I was fortunate enough to be using Aegis for the accounts that offer TOTP 2FA.
I now have access to about 8/52 accounts.
