Yes, I don't see any reason to red-light any of these groups, as groups ... except potentially on a case-by-case basis (don't go to this or that priest or "priest" or chapel). IMO, "Indult" / "Motu" / "Ecclesia Dei" are getting to close to having very few validly-ordained priests left in those groups ... but you will occasionally find an SSPX-ordained refugee in one of those groups, and some of them do have Mass in the same churches where the NOM is also held ... yet there are some dedicated FSSP / ICK types of "chapels" / "parishes" (though even for these many or most have at least one or another doubtfully-ordained priest). So perhaps Indult is closest to red-light ... and I would definitely give them a hard Orange.
