I'd argue that a lot of those elements are remembered fondly (and thus reused), because they are clear improvements on the mythos.
Are they? The changes to Lois are definitely improvements, but I don't see how any of the others are objectively better. The crystal architecture was striking but kind of silly if you think about it (where the hell do they sit?), and I got tired of seeing it decades ago. Ursa is just a renamed Faora, so that cancels out; Non is just a mindless thug, less interesting than other Phantom Zone villains from the comics. Making Jimmy a photographer instead of a cub reporter has some merit, I guess (and his original radio job as a copy boy is obsolete now), but you can get good stories out of him either way, and a lot of versions make him both. Eve has no advantages as a character over Mercy Graves (also a creation of an adaptation, specifically
Superman: The Animated Series), and Otis is a joke; I feel both characters diminished Lex Luthor as a villain, since you'd think a true criminal genius could recruit a better gang than a couple of idiots. Even the goons-of-the-week in
Batman '66 were more competent than those two.
And Jor-El's ghost... Some good things have been done with the idea, like in
Man of Steel and with a similar character in the
Krypton TV series, and arguably in
My Adventures with Superman, though it's still a bit too early to tell. But it's never been a concept I've liked all that much, and sometimes (as in
Superman & Lois) it seems to be used purely out of a sense of obligatory mimicry. There have been multiple worthwhile versions of Superman that have done just fine without it, like
Lois & Clark (the first couple of seasons before it went to crap) and S:TAS.
Honestly, one reason I get tired of everyone copying
Superman: The Movie is because it really
isn't all that good an adaptation. In some ways, it's fantastic, but in others it's pretty dumb. But it's the version most familiar to the general public, and that's why it gets imitated, the bad with the good.
