On proper public wifi, you can't see anyone else's traffic. On the poorly configured ones, everyone sees everyone else and you have no clue who might be sharing that space with you or what they might be doing. Or what malware is on their machine scanning for open ports, trying to sink it's teeth into yours. (Windows does give you the option to declare a LAN as "public", which closes some of those ports.)
Ultimately, managing IT security and privacy is about balancing risk/exposure with convenience/usability, and we all have to draw our own lines. I'm careful with my own stuff, generally choosing to use my phone as a hotspot whenever it has a usable signal. Mrs -jk works in a high profile office; their systems are very tightly managed.
Make sure you stay current on all your updates, don't use stuff no longer being updated (glaring at you, Android!), and keep your brain engaged. Or get off the internet altogether. As Joshua said, "Strange game. The only winning move is not to play."

Solid points, except for the very first. I don't think they are "poorly configured", in fact I think it's pretty impressive what a public network can do. On the whole, they are optimized for efficiency.
And as the rest of your post points out, security be damned. Take your chances. (I take mine all the time, but then again I'm usually browsing Facebook, which is always so way secure on its own. )
