Ungoogled chromium is a good alternative in terms of privacy because all google-related services are gutted and there are no other built-in telemetry things.

There are some downsides, too.

First, you have to do some research on learning to make this browser work conveniently, e.g. finding alternative services to sync and backup your settings, bookmarks, accounts and passwords, etc.

Second, changes pushed by Google like Manifest V3 is still hard to deal with.
