There’s no official support for non-Google phones yet. As always, keep in mind that these are betas for a reason and still mostly meant for developers who want to test their apps against this new version and early adopters who just can’t wait for the stable release. Things can — and will — break.
For the most part, there aren’t many new features in this beta version, though there are two user-facing UI updates worth calling out. The first is a new back arrow (yes — we’ve reached the point in mobile OS history where new back arrows are pretty much the most exciting thing). As Google notes, the gesture navigation experience now “includes a more prominent back arrow while interacting with an app to help improve back gesture understanding and usefulness.” This arrow will match your wallpaper or device theme. Exciting stuff.

Developers will now also be able to add custom actions to the system sharesheet, and the sharesheet will now be smarter about how it ranks your sharing targets.

Otherwise, there isn’t all that much new here. Per-app language settings are here, as are Google’s previously announced new privacy settings.

I expect we’ll hear a bit more about what’s new in Android 14 — and see more user-facing features — at Google I/O next month. For now, though, this appears to be another evolutionary release.
