Have you checked out Arc? I switched the other day and their approach to somewhat-permanent "tabs" is interesting. At first I missed bookmarks but then I realized that what they were doing is actually closer to how I want to use the browser.
Arc (macOS) is ridiculously good though. It's become difficult/impossible for me to use another browser happily the past few years. I wish they were focused on it instead of their mediocre AI browser project. They decided to claim Arc windows was out of beta when it's still vastly worse than the mac version in just about every sense. But at least they got the core tab management features locked down (from what I've heard, I don't have a windows machine to try it on.)
