There are keepass android apps like [KeePassDX](KeePassDX (Secure and open source password manager compatible with KeePass files.) https://f-droid.org/packages/com.kunzisoft.keepass.free/). You can have server sync with WebDav, but I don’t know about shared databases. Should work if you configure the WebDav server etc.

A friend of mine is a big fan of bitwarden but I have no Idea if that fits your requirement. Should have a webui tho.

I don’t know about the ID and drivers license, but banking is no problem as you do not root the phones anymore. You can even use the google wallet if you want. I think the only thing not there is the google safetyNez verification, even tho you can install apps through the playstore. So I don’t know if the apps can determine if there on an official build or not.

Edit: Please take my words carefully as I’m only in the experimentation phase myself. All I really can say is: my banking app and PayPal work no problem

See if you can install LineageOS on it. Replaces all the dog shit and has opt in for the google services etc. if you value your privacy.
