For 2fa, I highly recommend 2fas -- it is free, open source, available for web and mobile, and it's interface is smart. Lots of 2fa apps are stupid, Google auth included. Authy is especially stupid. Bitwarden also does 2fa, and it's super convenient because it adds the code directly to the clipboard usually.
For notes, consider obsidian.
