I've had a variety of programmable thermostats over the years in different
homes.
One thing that I would really love is to see the cumulative running times
over a period of time.... day, week, etc. -
Are there any home thermostats that maintain these running times ?
It would be great to see any differences when changing temps, or programs.

Years ago we had a Hunter programmable which kept a gross running time
(no breakdown by day, week, etc.); maybe their current products do the
same or more.
It blew up from a power surge induced by a nearby lightning strike and
was replaced by a Honeywell thermostat which doesn't have that feature.

I had a Hunter and it measured running time. I also have another stat that does
it. I think all the fancy ones have it. It was neat the first year I was in a new
house with an old 55 year old oil burner. I could predict how many gallons
of fuel used by gallons per hour. I think it was 3/4 gallons.
The Hunter ran off the furnace supply and had the battery backup.

Most have a air filter monitor that measures hours

I've never seen a stat like that, even in the comercial market.
Instead, get a data logging program off of the web, a couple
channels of A/D input (PCI card or USB dongle), and a thermometer
with a data out (that part is optional). Wire another pair across
whatever contacts you want to monitor [Heating or Cooling] on the
stat and run them to your PC. Them just gather data to your
heart's content. At minimum you get runtimes forever. If you add
the thermostat, you can actually see the temperature swings. Add
another thermostat somewhere else in the house that you are
interested in and you can see how well your heating/cooling system
is actually performing.
Otherwise, just pop a run-time meter across the fan motor. That
will give you accumulated run-time, but without the time ticks and
time of day you can get from the logging software. A lot cheaper,
tho.
