Apols if this post is best sat elsewhere.
On occasion I've muxed a movie or TV episode whereby before actual viewing I wasn't sure whether there were any non-English speaking parts, and may not have been obvious within e.g. AP, Nfx or other places on the web, such as that very helpful site with the shared and occasionally updated spread sheet resource I've made good use of. Or such as Subscene (other flavours are available), where I'd search for 'foreign parts only' or 'non-English parts' but discovered there was not always anything obvious for some titles.
So I did some experimentation and out of curiosity I downloaded a Korean version of subs which on my closer analysis gleaned that I could do a <Ctrl> - F find search for all characters with the quotation symbol (") which tended to show the timestamp for (1) English only dialect parts (obviously the text was still in the Korean format), and (2) English signage, such as when a location pops up or some other non-spoken parts have been filmed e.g. the text on a phone or computer VDU.
Ok, so the hits were still foreign to me but I was then able to grab a full English .srt file and by simple data washing fairly quickly could marry up the Korean 'hits' to the English spoken counterparts.
Of course, there wasn't always a Korean version present but in another test, I found by interrogating a German .srt file that all the English dialect and signage, albeit in that native language, happened to be capitalised, so this ultimately also helped me remux a movie how I wanted. I'm guessing other languages may offer similar clues ?
I have only had to do this for a handful of flicks, and didn't find this process unduly time consuming or laborious, and was careful not to concentrate too much on the English dialogue being copy / pasted into the relevant time stamps to help avoid any potential 'spoilers' for my future viewing.
I don't know if there may be easier methods perhaps a few wizened folk out there may know about? Either way - being the caring / sharing chap that I am - hopefully this may assist others in a similar boat.

That's an impressive process and investigation that you did!
