Hi Future-Craft,
When you have Cinema 4D, you have Red Giant's Magic Bullet Looks. There are a few plug-ins avaialbe. I have "scanned" (Red Epic Dragon) over a hundred of my filters for the Optical Diffusion, and the Red Giant team has turned those into data for the optical Diffusion Filter, for example. Most of the RG magic Bullet Looks filter has gotten this practical care. For example, all the Film emulations are based on practical footage.
Here is an example:
CV4_2024_drs_24_RSmb_01.c4d

Perhaps too much was added for the demo, but you can drag each effect out or add more.
Here is an ST-Map maker file with distortion; set the render to save path for the UV-pass in the Multipass setting (Standard Render!)
CV4_2024_drs_24_REst_02.c4d
Then load this file into the RS Camera>Optical. You might need to widen the Field of view.
I checked your file and did not touch an unknown download server. (Dropbox is preferred, but Google, Adobe, Apple, and Wetransfer can pass the security here. Sorry about that.
All the best
