Ceramic pans vs PTFE pans
I can address a few of your points.


Polytetrafluoroethylene (Teflon) is the third most slippery substance known to man (the first two being incredibly expensive - an alloy of aluminum and Diamond-like carbon).  There is nothing used in home cooking that is more non-stick.
Teflon pans are NOT highly vulnerable to normal use with metallic utensils.  Just don't aggressively scrape them.
Teflon's safety is related to off gassing under high heat.
Ceramic is a loaded term.  There are many, many coatings that are ceramic, and they all have different properties, where as PTFE is exactly one type of coating.  Judgements of 'ceramic' are not really reliable.  A specific pan or coating technique are the only tangible thing that can be judged.
