And for reasons I don't fully understand, somewhat unrelated - if you look around almost any small business in my area, it's almost always VGA, rarely DVI, almost never HDMI or DisplayPort.

My theory is just that the cables came in the box and are screw-on when more modern connectors are friction fit, and the IT departments don't want the hassle of "they just got pulled out." Which should have been predictable - but I can literally see 12th gen Intel, paired with 1080p display, over VGA fairly regularly.

It's 100% because the VGA cable came in the box. Nothing about cables pulling because my lazy counterparts would not even screw in the DE15 cables half the time.

DisplayPort has latching connectors, but they're easily broken when pulled out without unlatching.

For some reason DisplayPort monitors are more rare, and even when you get one like the MSI Pro MP241, it comes with an HDMI cable in the box!
