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.
