Best choice for publishDate and search is MWEB:

date 3 search true size 387527 {MWEB 2.19700101}
date 3 search true size 574903 {WEB_REMIX 0.1}
date 3 search true size 974833 {WEB 2.20210223.09.00}

publishDate

An alternative to publishDate is:

"text": "Published on Nov 5, 2020"

which you can get doing a next request with IOS_KIDS. Uncompressed size is 115 KB. For publishDate, doing a player request with MWEB, you get uncompressed size of 57 KB.

Since ANDROID is smaller, we want to pull as much from it as possible. Here is what we need to check:

StreamingData struct {
   AdaptiveFormats []struct {
      Bitrate         int64  // pass
      ContentLength   int64  // pass
      Height          int    // pass
      Itag            int    // pass
      MimeType        string // pass
      URL             string // pass
   }
}
VideoDetails struct {
   Author           string // pass
   ShortDescription string // pass
   Title            string // pass
   ViewCount        int    // pass
}
Microformat struct {
   PlayerMicroformatRenderer struct {
      AvailableCountries []string // fail
      PublishDate        string   // fail
   }
}
