I use 1Password, and they have an easy CSV export. The lock-in is very weak.

If they were to suddenly disappear, or I can't pay for it, I still have the local copies on my devices that I could export and move to some other system.

I started off with keepass, then moved to lastpass for better sync, then moved to 1password because I didn't like how lastpass works. Each of them support various forms of exporting/importing logins, so there's not much risk of vendor lockin with those. I'd assume it's the same for other managers, but you'd have to check.

My biggest issue has been that I only saved passwords when I started with keepass instead of username+passwords, which lastpass all imported as secure notes instead of logins.

There are at least several apps for each platform that can work with KeePass files.
