The Ancients managed to keep track of the complex gearing

About the bikes: "Eroica rides are organized exclusively for
Bici Eroiche (Historical Bikes); road-racing bikes built in
1987 or earlier, both with and without gears. These bikes
normally have a steel frame with shift levers on the down
tube and brake cables that must pass outside and over the
handlebars. Pedals should be with toe clips and straps;
quick release or clipless pedals are not allowed."

Sounds wonderful, much like my morning rides (without pesky
gear changers on my fixie).

Riding a fixie is not conducive to my pedaling technique, but it seems
to me that riding a multispeed freewheel/freehub bike without shifting
is almost the same thing, only better because you don't have to plan
your cornering so that you're not doing with your inside pedal down?

Not quite, with a single chainring/cog does make the bike lighter, and
simpler maintenance.

A fixed gear is also significantly more efficient - fewer drivetrain losses that are exacerbated but poor biomechanics. A derailleur-tensioned chain on a freehub allows poor pedaling technique. The fixed-gear "hides" this as the 'return' from the forward motion of the bike keeps your legs moving in circles (rather than "pedaling squares"). As the speed and cadence increase, it trains you to be more efficient since bad pedaling technique limits your ability to spin. My favorite quip WRT to fixed gears is 'in any given gear, a fixed drivetrain is more efficient'.

 And folks do like the fixie ie no freewheel feeling, I missed the ability
to freewheel too much and being an old MTBer like to move on the bike so I
used a freewheel.
 Used to be very fashionable about 10 years ago back to seeing them now and
then.

It's still pretty rare around here, but there is a small hardcore group that races here: https://nevelodrome.com/
