I have Armbian_21.11.0-trunk_Rk3318-box_hirsute_edge_5.14.14_xfce_desktop running on a Z28 (original). This has the RK3328 SoC with an RTL8188 WifI chip. Quite acceptable.
I replaced xfce with mate following:
and a lot of tweaking.
I also am running the xRDP server following https://www.hiroom2.com/ubuntu-2004-xrdp-mate-en and https://github.com/neutrinolabs/pulseaudio-module-xrdp/wiki/README , with a bit of tweaking.
I can give more details if anyone expresses interest.

There are two issues that I would like some help with if anyone has any info to share:
1. RTL8188 WiFi chip is not recognized
2. My (admittedly cheap) HDMI TV is recognized as 1080P 30Hz. However other devices I connect to it do use 1080P 60Hz. These refresh rates are as reported by the TV in an info panel that reports the HDMI connectivity status.
