Haven’t done it personally, but I think Ubuntu would be one of the better choices. You get the Ubuntu ARM debs and ARM snaps out of the box.
You can then install Flathub and Fedora Flatpaks.
Fedora Flatapks is small and not without controversy, but one of its benefits is that all of its packages are built for ARM. Flathub and Snap aren’t consistent in doing that. Any many times you’ll find that Snap has an ARM build and Flathub doesn’t, and vice versa.
