I don't think I've heard perseveration before? I still hear special interest used around the place pretty often? The special interest is autistic/hyperfixation is ADHD split is fairly solid.
It seems to me like it's ... really common for ADHD symptoms to get watered down into more-universal experiences in a way that seems kind of like what's happening here? At least in the first example. (e.g. if all dads have it then it is presumably not any kind of neurodivergant trait and thus probably best described as a regular interest or dare I say it, a hobby? which, uh, the point of split between "special" interest and regular interest is one I spend an utterly pointless amount of time stressing about, considering it's cosmic insignificance)
(but also that second example you posted I did in fact take to mean the more ADHD style "I have spent the last 48 hours doing as little as possible but think about this shiny new thing I care about a lot" which seems like classic hyperfixation?)
less related but that post about using a special interest to explain how romance is, is ... really compelling? I want that thing, of having a person who is compelling and preoccupying like an interest is! (and, uh, I would quite like someone else to have that thing about me, too, if I'm being selfish). Not hugely novel as a perspective to me but *really* compelling? Also not really sure it's how my brain works but *sighs longingly*.
