Extra information
When downloading the Video with youtube-dl the English audio track is downloaded by default
btw for me it uses the spanish audio by default.
i would say it's up to youtube-dl what is selected and they apparently added a filter for the audio language https://github.com/ytdl-org/youtube-dl/commit/9c1e164e0cd77331ea4f0b474b32fd06f84bad71. this needs to be incorporated in the youtube format option.
it also seems that youtube doesn't give us any audio language info for the various audio tracks?

Yeah, youtube or youtube-dl do not clarify which audio language is being used, so this can't be automatically determined.
On this specific video, 251-0 seems to be english, per manually parsing the URL for the string "lang%3Den", but I'd never seen different languages being available before, nor have any idea if 251-0 is always English.
I'd say you probably should explicitly specify you want the format 251-1 to be used, if available (if it's always Spanish audio), as in --ytdl-format "bestvideo+251-1/bestvideo+bestaudio"
To show more than just one audio and video track , you have to use the all_formats option for the ytdl_hook. Unfortunately that option isn't without it's issues (e.g. #10394), but I already have a few PRs open to improve the ytdl_hook and I hope that one day it will be able to completely replace my quality-menu script.
In the meantime I've added the ability to show any fields from yt-dlp/youtube-dl in quality-menu after seeing this. The default configuration now shows the language code of a track when available.
yt-dlp has a --format-sort option that accepts lang to sort by language preference, but I don't know how to set that preference (--format-sort lang:es didn't work).
As previously mentioned, you can list more formats with all_formats, so I think the fundamental thing behind this ticket, "not showing all audio tracks" has a solution (the other noted drawbacks are separate things).
