You aren't going to have all your accounts able to use Google, not everyone offers it. So you are going to need to use a password manager in any case. I use Bitwarden and like it, my wife uses it but is only ok about it.
Now, as far as Google vs. Password manager on sites that do support it: Google can be convenient, but there is the infrequent, but apparently very real risk of Google locking your account, and through that also locking these other accounts. I'm not very concerned about that risk personally, but I also would be very reluctant to put important accounts like banks and bills on a Google SSO.
To be clear: I'm not a big "google is evil" guy, but "I'm locked out of google" seems to be a regularly recurring story, but it clearly is low frequency. I do know that when things go wrong, Google is often a black box with little recourse or even any way to contact someone there, especially, I imagine, if your account is locked.
I, personally, almost always use a password manager rather than a Google SSO, just because I have it set up an it's almost as easy as the SSO.

Or the very real scenario where you've been using a free Google Workspace account (is that what it's called these days) with a custom domain, and suddenly Google wants to start charging you for it. Meanwhile you've "logged in with Google" using that account across many, many sites and Google hasn't offered anyway to migrate away from that. So you either pay up or lose access to any of those accounts.
