Take a look at KDE again, won't hurt. I switched to openSUSE Tumbleweed (best integration IMO, since its their standard DE since forever plus rolling release and btrfs snapshots on upgrades) from Cinnamon on Mint. KDE connect was the app that made me give it a try, more than happy with it. The devs made resource usage a priority, nowadays it rivals and sometimes surpasses XFCE which got heavier in the meantime.
