Alright, I'm now looking at several folders I've kept of installs and updates, but because GOG doesn't concisely list what or the order things should be installed, I'm now going crazy with trying to understand what should be installed and in what order.

Here's the folders I now have for the game:

Cyberpunk 2077 (base game)
Cyberpunk 2077 2.0 (full game with the 2.0 update)
Cyberpunk 2077 Phantom Liberty
Cyberpunk 2077 2.0 Patches
Cyberpunk 2077 2.1 Patches
Cyberpunk 2077 2.2 Patches

Alright, so... the patches bring the game and DLC up to the next version.

With the files listed above, when ever I go to reinstall the game, what order would I now install everything?

Also, is Phantom Liberty already at the 2.0 update, since the update was released first?

I'm assuming I don't have to bother with the base game, since I have the 2.0 version.

So would the install order be: Cyberpunk 2077 2.0, Phantom Liberty, then 2.1 and 2.2 patches?
Would it be that simple?

If the DLC is already inclusive of 2.0 then I'd assume that's the order I'd need to install in, for future reference.

Any help would be appreciated, thanks!

How I installed it and in this order:
1. CP2077 2.0 Full Install
2. CP2077 Phantom Liberty DLC v2.0
3. patch_cyberpunk_2077_2.0_(67690)_to_Build_4902785Change_6408866_with_EP1_RL_(67718)
4. patch_cyberpunk_2077_2.0_PhL_(67791)_to_Build_4912681Change_6422997_0_(68001)
5. patch_cyberpunk_2077_2.01_(68001)_to_Build_4940722Change_6460039_0_(68508)
6. CP2077 PL 2.02 Full DLC - setup_cyberpunk_2077_phantom_liberty_build_4940722change_6460039_0_(64bit)_(68508)

Notes:
I was playing w/ PL DLC from step 2.

WARNING: If you do Step 3 before step 2, the game will have LOTS of bugs and crashes (at least it did for me) and will require a full reinstall in the order listed above to fix it.

Step 3 patched PL and still allowed me to play the game normally with the DLC. No need to reinstall the PL DLC.

Step 4 Will patch only the main game and you lose access to the PL DLC (v2.0). If you want to play 2.01 with the DLC (2.01) you have to downloaded the Full 2.01 DLC and install it after this patch.

Step 5 will patch only the main game to v2.02 and you will lose access to the DLC, so you have to download the 2.02 DLC and install it again to be able to play it again.

So it looks like the standalone patches only affect the main game. Every patch will require you to download the PL DLC for that patch.

I was asking the same to GOG support, and they asked me to provide a video showing the problem. XD
