What about vaccination? What about data? What about metadata?
I suspect for data and metadata the answer is "the 4th Amendment covers that, see 4th Amendment jurisprudence", but that's not enough because that only limits the state and state agents, and even then not at all as to metadata, and barely as to data.
Many of the landmark privacy-as-bodily-autonomy decisions are related to reproductive health, but there are others. McFall v. Shrimp is another important case in the area and concerns forced medical procedures rather than reproductive health: https://en.m.wikipedia.org/wiki/McFall_v._Shimp The court found in that case that an individual could not be compelled to donate bone marrow, even though it was necessary for another to live, because that would violate "the sanctity of the individual."
Lol, then I've got a bridge to sell you. Thomas dissented vociferously in both Lawrence and Obergefell, it's clear he wants to overturn them, not even he is trying to hide that fact. His Obergefell dissent was especially nauseating because he was trying to say how we was so "offended" that Loving was even construed to be analogous to Obergefell.
He's a typical "I've got mine, fuck you" conservative.
