Oh, we gonna fight here. So in Star Wars, the droids land and are picked up (droid-napped) by Jawas, scavengers that SPECIFICALLY scour the wasteland looking for junk to sell. They are then, after an unspecificed period of time, taken to basically a swap meet where they are bought by Luke and it's C3POs agency to make sure A2 comes as well. Obi-wan is near Luke BECAUSE he is watching over him. So sure, there is a big eye-roll in retrospect, but it's all supported by the story in a plausible way
Ripley slips past "the core systems" and sacrifices her entire life in that sleep. Her daughter grows and dies in that time. So she doesn't just "get picked up out of the blue", her prolonged sleep is FUNDAMENTAL to her character drive in the film. And when she does get recovered and tell her story, THAT is the reason why Hadley's Hope colonists are told where to go, otherwise that alien ship might have sat there for decades longer, if not forever, until the new terraformed world eroded it away. Again, a bit of an eye roll, but all supported by and critical for the story. And Ripley's PTSD from Alien is the motivation to go out again, plus she has no family other than Charlie, who stays behind.
We'll see how Romulus weaves in the xeno. But I consider Prometheus and Covenant to be totally separate stories from Alien. About all you could say is the initial response to the distress beacon and Ash's actions are slightly colored by a specific desire to recover the xeno versus a general order to recover ANY potentially useful alien life (it's still a bit vague how much alien stuff, particularly non-xeno, is actually known about in the Alien universe from those first films).
