It reminds me of the train derailment stories last year, soon after the disastrous one in Ohio. Trains apparently derail quite often, but it was on everyone’s mind, so any outlet that posted about a more mundane derailment was rewarded with clicks.

Precisely this. There's a thousand train derailments in the US annually; most incredibly minor. For a few weeks they all made the news.

The media is picking up any Boeing related incident and it is ignoring other incidents. Most of the incidents I read about in the last weeks had nothing at all to do with Boeing as a company.

yeah the media absolutely is. this is the copycat effect (maybe there is a better name for it?) but essentially this you can see in media all the time whenever there is a big story.

If it bleeds it leads. They are most definitely exploiting cognitive biases to get eyeballs on their stories.
