As per usual, I agree with your comments on Bergonzi in the main. However, I can't help pointing out that the Philips I Lombardi doesn't feature Bergonzi, but the main tenor part is taken by Domingo.and his contributions to the Philips early Verdi series, I Lombardi, Attila, I Masnadieri and the Orfeo Oberto.
I would agree with the OP that Bergonzi never made a bad recording, but I'm afraid I find his singing overly refined and he lacks excitement. If I had to choose a favourite, it would be his Aida with Price from the Met, where he is much more involved than in his studio recording. I would probably go with his Ernani (again with Price) as his best studio recording.
