Welcome! Glad you got it done at last. You've done a very important and huge step in securing yourself already. Confirm you've gone through the post installation steps and
rockhopper99 like rooting phones
don't do that.
You should also sign up for a password manager whilst housekeeping already. If you don't know the concept yet, the idea is simple: you remember only one password, with it you gain access to all your other passwords and account details. This allows you to setup unique, super strong passwords for each of your accounts because you don't have to remember them. And that's important because reusing the same password - including slight deviations of the same one - is a recipe for disaster given how many sites and services are constantly breached. Once it's out there all your accounts could be compromised at once. There are a handful of good choices, I recommend you Bitwarden. It's free, well established and convenient because your passwords are stored in the cloud.
You also need to setup two factor authorization on your accounts, especially for your password manager and e-mail. 2FA stops an attacker dead in their tracks from gaining access to an account, even if they happen to get their hands on your password. Every time you login you must also enter a typically six digit long numeric code that keeps generating new in your 2FA app. So an attacker would need physical access to your phone on top of knowing your password to breach your accounts. Aegis is top notch in this segment, no questions asked really.
Last but not least...backups. Backups of your important documents, backups of your passwords, backups of your 2FA reset codes for when you may lose your phone or it dies, backups, backups, backups!
