Comlink-X, G D Em C is the same as C G Am F (I V vi IV).
Em C G D is the same as Am F C G, which is also a very popular chord progression, especially in the last decade or so. Some Jewish songs definitely use it — see by googling “A F C G” or “Em C G D” and “Jewish guitar chords.” For example, Finally Here by Ari Goldwag uses this progression. Smile by 8th day uses it in part of the song.
C Am F G (the 50s or “doo-wop” chord progression), was very popular in the 50s and is still sometimes found today.
