I simply can't believe there isn't some incentive for longer videos. It may be that YouTube only cares about total watch time and doesn't care if a creator pushes lots of short ones or a few long ones, as long as viewers keep viewing. I see so many videos like this:

Tie Shoes Like a Pro "If you're watching this video you probably want to know the secrets to good shoe tying. We'll show you how in this video. It's surprisingly easy, so don't go anywhere. But first, have you ever wondered why we tie our shoes? The first shoes weren't actually tied but were just soles that people nailed to their feet. <Cue hammer sound effect and scream> Haha, actually this didn't hurt at all because... <10 minutes pass> ...and then in 1890 Eritrea was founded, but you don't care about that! Haha! You're here to learn how to tie shoes! Don't worry, we'll get to that too! Anyway, also in 1890 all the leather factories in France burned down and so they couldn't spare leather for shoe buckles, so they began using bits of string..."

The "youtube meta" has changed overtime and not all creators have stayed current with it, so you can find old videos which were once optimized for youtube but no longer are, or new videos being created in an outdated style. With some channels though, I think they've decided to make suboptimal videos from the youtube algorithm perspective because they're getting most of their revenue from a loyal fanbase donating to them on patron/etc, so they cater to the preferences of that specific crowd.

There could be multiple valid strategies too. I’ve seen some creators will put out a video once every few months, but that video will be shown on everyone’s feed and will get millions of views. While mass content posters like gaming channels probably get less exposure or their videos spend less time on the top.

True. And different kinds of content may have different metas. Some content needs to be timely and can only get views for a short period of time before effectively expiring. Other content is evergreen and can play the long game, counting on getting reliable view numbers for years.
