Provide a description that is worded well enough to be understood

The same resolution is displayed for each format of the same video, even though on Facebook, you can see different resolutions that do not match the output from YT-DLP. For this link, https://fb.watch/vv4KcJ16Ft/, we get seven instances of 1280x720, while it should show different resolutions for each result.

Provide verbose output that clearly demonstrates the problem

[X] Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
[ ] If using API, add 'verbose': True to YoutubeDL params instead
[X] Copy the WHOLE output (starting with [debug] Command-line config) and insert it below

Same result with the user agent

you didn't post the actual formats table?

The resolution list of this video webpage is fake (may be site changes in progress) You can check it by following the steps below:

open https://fb.watch/vv4KcJl6Ft/ in browser WITHOUT login facebook (you ran yt-dlp without facebook login)
pause playback
launch developer tool, open the "Network" tab then clear the log
choose 640p
you get new lines in the network log
look for the URL similar to this (type is "fetch" in chrome or "mp4" in firefox): https://video.fhkg3-1.fna.fbcdn.net/v/t39.25447-2/463483456_2922988664517678_2013884078709851073_n.mp4?_nc_cat=100&ccb=1-7&_nc_sid=9a5d50&efg=eyJ2ZW5jb2RlX3RhZyI6ImRhc2hfcjJhdjEtcjFnZW4ydnA5X3E4MCIsInZpZGVvX2lkIjoxMDAwNjg4NDc1MDc1OTgzfQ%3D%3D&_nc_e2o=1000688475075983&_nc_ohc=adkQeTOILx8Q7kNvgH2RLm3&_nc_zt=28&_nc_ht=video.fhkg3-1.fna&_nc_gid=AnxIHgw6KJD0xp59hiy0VMN&oh=00_AYAJVklTSYZVPNrfCsdUKa08l3pvDJ4Idg8o2c1Hmr2b4A&oe=6725A255&bytestart=0&byteend=825 (your URL will not be the same as this due to different timestamp and location)
remove the bytestart and byteend parameters at the end of the url
open the url in browser and right-click to save the video
check the resolution of the saved video. You get 1280x720
choose 480p
repeat the step 5-9 above the URL looks like this: https://video.fhkg3-1.fna.fbcdn.net/v/t39.25447-2/463391795_4001208383478235_3494695673428672294_n.mp4?_nc_cat=104&ccb=1-7&_nc_sid=9a5d50&efg=eyJ2ZW5jb2RlX3RhZyI6ImRhc2hfcjJhdjEtcjFnZW4ydnA5X3E2MCIsInZpZGVvX2lkIjoxMDAwNjg4NDc1MDc1OTgzfQ%3D%3D&_nc_e2o=1000688475075983&_nc_ohc=buevBAQV354Q7kNvgGHnrlJ&_nc_zt=28&_nc_ht=video.fhkg3-1.fna&_nc_gid=AnxIHgw6KJD0xp59hiy0VMN&oh=00_AYDPl5RlOqWbzsVCHUIZMg5eUyYtV1Ux_9DT2mS3u81tJw&oe=6725B771&bytestart=0&byteend=825 which is also a 1280x720 video
choose 240p
repeat step 5-9 above the URL looks like this: https://video.fhkg3-1.fna.fbcdn.net/v/t39.25447-2/463366874_567428675707391_862087812479695912_n.mp4?_nc_cat=109&ccb=1-7&_nc_sid=9a5d50&efg=eyJ2ZW5jb2RlX3RhZyI6ImRhc2hfcjJhdjEtcjFnZW4ydnA5X3EzMCIsInZpZGVvX2lkIjoxMDAwNjg4NDc1MDc1OTgzfQ%3D%3D&_nc_e2o=1000688475075983&_nc_ohc=NvuFjs3eJEcQ7kNvgHGXE3s&_nc_zt=28&_nc_ht=video.fhkg3-1.fna&_nc_gid=AnxIHgw6KJD0xp59hiy0VMN&oh=00_AYC3osQGvDtEFpmnQaSUC0rE4jPMlLH3_vYyxluU5Z73ZA&oe=67258E16&bytestart=1113052&byteend=1212997 It is a 1280x720 video too

For https://fb.watch/vv4KcJl6Ft/, all resolutions are served by a 720p video (but not the same 720p video). The output of yt-dlp is correct.

If you perform the above check on another video, such as https://www.facebook.com/radiokicksfm/videos/3676516585958356/, you will download videos with different resolutions (720p and 360p for this example)
