It all depends on what version or variant of OS you are using. I have a R6C and have done many fixes and workarounds for various OSses/distros to the point that I just maybe take what generic upstream kernel does. I anyhow change/fake MAC addresses as I use bridges and also VLANs. Is in Armbian Bookworm and Opensuse Tumbleweed. Ubuntu based has and extra netplan layer that is even more a PITA as it keeps .nmconnections file also in another place (generated) then /etc/NetworkManager/system-connections/ Recently a change in scripting has been done so that name 'wan' is/or has been changed into 'wan1', so at least this does not match what is printed on the metalcase. At least that is what I remember from a quick check on github; See what is in your udev rules scripts yourself. https://github.com/armbian/build/blob/main/config/boards/nanopi-r6s.conf

it all depends on what your plan is what the device should do; I have a R6C for about 18 months now and bought it as an alternative/better more integrated alternative for existing RPi4 (and also RPi5 that still has no M.2 socket). I see many people on for example RPi forum who want to create some router thing, so they buy HATs and USB stuff for an RPi, but this NanoPi series has even WRT preinstalled. I removed it as I wanted generic server box (virtual machines host mainly). I do not really need the 2x RJ45 currenlty, but the metal case is great. Is simple passive cooling and insect/animal proof. It is mainly bootloader and kernel (and DTB/overlays) that matter. The userspace can be taken from elsewhere if you know how to. I currently use the R6C as desktop as well in another cooler room (summer hot here). EDK2-UEFI v1.1 bootloader, Armbian edge 6.16-rc3 kernel, Opensuse Tumbleweed for Btrfs rootfs to drive a DVI monitor KDE plasma 6.4.x. It means various Rockchips HW blocks do not work like NPU and video codecs HW accel block, but that is a choice. If you need those, use vendor kernel and see what exctly you need/want. The 2x RJ45 might be a chalenge, see maybe also:

I also needed a desktop on my Orange Pi Zero 2. I installed an "Armbian 25.5.1 Bookworm Minimal / IOT", then installed an XFCE desktop using some short guide I found on the Internet: sudo apt install lightdm xfce4 xfce4-goodies xorg After a reboot, my desktop started without any additional configurations. It's so good that now I have a new system with a desktop on my old hardware, which doesn't provide fresh OS images anymore.

That is a lot of work to get video for TVs that today have HDMI anyway. The audio out for an orangepione would also require audio amplifiers. Not many people have the skills to solder to the tiny pads on the orangepione and could easily destroy the board. HDMI for the orangepione works very well for both audio and video. That said, the orangepione with 512KB memory is under powered to run a desktop environment.

Alright, was described a bit weird so I assumed you were talking about some 3rd party image. I cannot tell what's the difference or if they work better than ours since I don't use or deal with those. Best you just give all of them a try. Bullseye is Debian old-stable and will soon become old-old-stable. So if you don't want to deal with multiple major upgrades, if possible at all, I'd recommend to start with Bookworm or even Trixie (which I assume will not introduce major breakage until finally released in August since most packages are frozen already).
