Objective: Secure & private password management, prevent anyone from stealing your passwords.
Option 1: Store Keepass PW file in personal cloud service like OneDrive/GoogleDrive/etc , download file, use KeepassXC to Open
Option 2: Use ProtonPass or similar solution like Bitwarden
Option 3: Host a solution like Vaultwarden
Which would do you choose? Are there more options ? Assume strong masterpassword and strong technical skills
Option 2. It's the most robust. You'll never lose it (provided you have the redundancy), you can use it offline, you can transfer it using a USB pen, it's available in all platforms, including web. I've been using this for 8+ years, on my phone, desktop, laptop, company computer, etc. I store it on a personal cloud (and on each machine, of course, by syncing).
