This file can be imported into Firefox with https://github.com/louisabraham/ffpass/ (Firefox doesn't support importing the passwords from a chrome profile on Linux). It shouldn't be too hard to import it into your password manager of choice, either.
Although it just got pulled, the just-prior iCloud for Windows supported Apple Keychain password sync, allowing a different GAFAM to manage your creds. There is a Chrome extension as well.

After it’s back, then a reasonably frictionless way to migrate from one of these to another would be to run them side by side for a quarter, using the old to supply the cred while accepting the prompt to remember it on the new.
As long as you can still access the old cred store some way, you’ll have most useful creds in order, and only have to look up an old one when accessing something you never use.
