Bitwarden, hands down. been using them for like 7 years now? have got nearly 300 accounts in the password manager, and is fully free. Haven’t paid a single penny to them. Autofill is possible, on both android and web browser, although you’ll have to set it up through an extension. Fully cross-platform. Used it on Linux, windows, MacOS, IOS, iPadOS, Android. you can access it via a browser, is open source and is hosted by Bitwarden if you want to.

it ticks all your requirements!
