If you're interested in getting most of this effect for free I highly recommend using the venerable Hald CLUT library found here: https://github.com/cedeber/hald-clut
These are lookup tables made using film scans and do a damn good job of emulating the film "feel" especially when used with HDR input without burnt highlights or crushed blacks.
I personally recommend RawTherapee for photo editing, which includes native support for these.
To further emulate the effect you can use a film grain overlay (hundreds available one google away) and a color-weighted bloom filter.
ffmpeg and OBS also natively support this LUT format, I'm sure there are ways to use them in the FOSS video editing suites as well, but I basically do everything in ffmpeg commandline nowadays so I don't have firsthand experience.
