I highly recommend KDE. I saw something saying it can run almost as light as XFCE. Cinnamon is fine, solid on Mint, but basic, not very inspiring. GNOME is different enough that I don't enjoy it, but some really like it. KDE is beautiful by default and I can tweak it to my heart's content.

I didn't try EndeavourOS. Lots of options, and you can install it on whatever distro. Kubuntu's good, Neon is nice but a bit less stable. Solus is nice but may have less software available.
