Your wifi card is listed so no problem there. Your card should be supported by the kernel but is not included as there is module for 8852ae and ce but nor for your be.
So you have to build out of tree from the AUR like @spikerguy said. Luckily there is one source.
Maybe is just bad luck. Aur is not a 100% reliable source as is not checked by Manjaro and depends on the uploader skillness. In addition to this usually there is little information about ( the driver is not for arm64 or pci bus?)
This code will build on any kernel 6.10 and newer as long as the distro has not modified any of the kernel APIs. IF YOU RUN UBUNTU, YOU CAN BE ASSURED THAT THE APIs HAVE CHANGED. NO, I WILL NOT MODIFY THE SOURCE FOR YOU. YOU ARE ON YOUR OWN!!!
This is really confusing. The kernel 6.10 seems that was not there when the code was updated. A user says has builded it with 6.9 kernel and works.
Anyway is 8852ae and works for be, so the manjaro module can be good. Could the pci bus be broken?
Moreover, regulatory.db is not working and yor router can refuse to connect making this effort useless.
And with Joshua Riek 6.1.43 kernels it sometimes work (with low speed and at times able to stream 1080p/60 youtube but most could not). Most of the time it does connect for whatever reason(s). The system says WIFI is available but just cannot connect – timeout.
So suspect it is RTL8852BE-CG driver for bsp-kernel-6.1 and may be also with mainline kernel for now.
Thanks. The edk2-porting/edk2-rk3588 looks a bit complicated to get it to work. Is it Debian/Ubuntu or is it Arch Linux? There are a lot of good info there. Will read up.
So taking an easier way on distro that have used before. Installed the latest Armbian-Noble-Gnome-6.10-rc3 just to see whether:
WIFI (RTL8852BE-CG) is detected, available and works
Initial test result:
WiFi (RTL8852BE-CG) is detected and system indicate it is available but it somehow could not connect/time out. The time out message is repeated may times.

Bluetooth is available and my old bluetooth mouse sort of work (but not very responsive compared to a cabled mouse).
The edk2 firmware is easy to use. You have to write It to a sd card and the sbc boots from there. Write a Linux live distro to USB and the firmware will load the kernel and the Desktop. Ubuntu is not a good distro for rockchip but fedora and opensuse can do well. You can try then and see if wifi works.
In case wifi works you can use this firmware with Manjaro but that is another history. Maybe you must change uboot or wait for a better Manjaro firmware.
With edk2 you won’t have Linux hardware drivers, instead you Will have another ones like efifb for the GPU. Of course nothing for VPU.
The idea is to check if you have a working wifi without any problem. If you are sure you have a fully working wifi then you can avoid this trial but reading your posts seems that you haven’t.
With this firmware you can also run Linux with DTB and kernel drivers but i don’t know if there’s any diference with uboot. Manjaro can run this way and is the fastest one for rockchip.
On mainline kernel (Armbian 6.10-rc3) or bsp-kernel-6.1.43-joshua-panthor-git I don’t have a stable WiFi connection yet. It is touch and go (most of the time not connected and even when connected, connection speed is NOT up to par compared to bsp-kernel-5.10.160). When WiFi is available on kernel 6.1.43 it is usable for streaming Youtube up to 1080p/60 usually. Just that it doesn’t get connected successfully all the time.
On bsp-kernel-5.10.160 WiFi is working well or as expected so far.
Flased edk2 firmware on a 1GB SD Card and tried to boot using edk2 firmaware but it will NOT recognize the non-uefi image that I have on NVMe SSD or example Armbian-Noble-Gnome-6.10-rc3 on SD Card inserted into USB-Hub with SD Card reader/writer.
I suppose the edk2 firmware only boot uefi images?
Based on what have been posted in the net, mainline kernel for RK3588 is not ready for prime-time Desktop usage yet. Many basic functions are not ready yet but it has come a long way, for example now that Panthor (GPU hw acceleration) is available for mainline kernel.
For example Manjaro-Opi5Plus-KDE-6.9.3-3 image, have NO access to USB 3.0 Ports yet but can access NVMe SSD. But in general stable and usable depending on your needs.
The WiFi issue I am facing might be unique to Orange Pi 5 Plus using the so called official WiFi module from Xulong Software RTL8852BE-CG. Other Orange Pi 5 Plus users using another WiFi module does not seem to have the WiFi connection or WiFi stability issue.
On Armbian-Noble-Gnome-6.10-rc3 on USB 3.0 ports are working but no HDMo Audio/Headphone Audio output and Chromium with vpu hw acceleration (support up to 1080p but no audio). WiFi is recognize but will not connect successfully.
For WiFi (RTL8852BE-CG) currently as far as I can tell, Armbian did a patch (from Xulong Software) to their kernel 6.1.43-vendor-rk3588, this might be the best chance of getting WiFi on kernel-6.1.43.
