In Raspian, there is on the top right (near the time indication) an clickable blue icon. Click on it , select your Wifi access point and enter the password.

At the moment only the Debian based Raspbian Buster is available for the Pi 4 and it works fine. The INDI library can be compiled and the indiserver can be accessed it remotely or you could setup a standalone system with some more effort.

First I tried a ram disk in memory, but that not helped a lot. Selecting in the driver option save to ram disk (SD card) rather then via INDI network communication helped a little.

But in the latest alpha version of CCDCiel the problem is solved and only the download speed from the camera to RAM is relevant (USB 3). Saving is done while the next exposure is running. The lost time between exposure is half of the previous values or less. This improvement will be beneficial for all CCDCiel releases. At the moment I can only test on the Pi 3 since my Pi 4 is broken.

What are the arguments against using Raspbian Buster a Debian flavor.? It 's ready, it works, has a large community of active developers and users and has the LDXE environment. For me it's great.

Unfortunally, I can't work higher the 1920x1080. It is a small package and installing is as simple as sudo apt-get install xrdp. For me it works very well.

Maybe you could try XRDP. It builds a second session rather then copying the existing session as for VNC. I use it for my Pi 4 but up to now in HD.

I don't think the Pi 4 was throttled. This setup was all local in the Pi 3 and Pi 4. No download via network

For local saving, the memory card has a significant influence. A class 10 can do 10 mbit/second. So the normal sequence is something like:

1) start exposure
2) download result from camera
3) save result
4) start next exposure

Patrick is already working on a improved CCDCiel version where step 2) and 3) are run in parallel. So a multitask operation. This would reduce the lost time (between exposures) to the image transfer time from camera to memory only. First indications are that the lost time will be half or less.
