Have you tried COSMIC yet? Maybe PopOS is worth a shot.
Some packages are a bit old at the moment but they have a release coming in April / May that will bring them right up to date.
Perhaps LMDE (Linux Mint Debian Edition) is worth a look as well.
Both options are similar in that they take a very stable distro base and layer on a quite up-to-date desktop.
They also feature clear direction and a predicable release schedule.
It IS the early days of GNOME. MATE started with the source code of the last GNOME 2 release.
