Klingerman01 Start by defining how you want to use GOS, what you need it for, and what your expectations are.
The first thing you should do is install a good VPN. I have the beta version of TorVPN (owner). You can also get a commercial VPN, and I would definitely choose Mullvad over Proton. NymVPN is also very interesting.
Try to prefer GOS apps over alternatives. Pixel Camera may be an exception (in a separate profile and without network access), as it unfortunately takes better photos than the native GOS app.
Definitely choose KeePassDX over everything else (Bitwarden, Aegis, 2FA*). KeePassDX provides all of this, so you don't need Aegis for one-time codes. Activate the magic keyboard in KeePassDX (it's the most secure solution). Alternatively, you can enable autofill. KeePassDX is your strongbox for more than just passwords. You can store payment cards and copies of documents - read the documentation carefully. But most importantly: set a strong password, which will then be stored in the Titan M chip. Then, instead of entering a password, you enter a login PIN, and the password will automatically be entered into KeePassDX. Alternatively, you can use your fingerprint - it's secure because you need to log in to your profile first. I highly recommend using a PIN rather than a fingerprint to log in to your profile.
As for other apps, less is more. Molly or SimpleX are also good recommendations. SimpleX provides secure notes, so you don't need a dedicated app.
