The other posters have given good info. I just wanted to add to try setting the fan to on instead of auto so it runs all of the time. This will help keep the air moving in the house and might help keep it cooler. Also make sure you check the filter and change it if you haven’t yet. See if your energy company offers an energy audit. that will tell you if you have leaky windows, doors, or insulation problems. I have shitty insulation but with the ac fan running all of the time I can keep the house @ 70 - 72 on a 95 degree day.
I’d also consider getting a second opinion from another HVAC company, you could have undersized ductwork or another problem that the first company isn’t acknowledging.
Two issues with running the blower all the time. One, wear and tear on the blower over time. More importantly though, the coils in the unit need occasional downtime to let moisture drain for best efficiency. Your points on moving air while not cooling are valid though, and newer thermostats do have a circulation mode that will cut on the blower for a percentage of the time the AC itself isn’t on to do move air around. Good for second story homes with one AC, as the thermostat is usually on the first floor while the heat rises to the top floor.

Yeah. I only do on all the time when the air quality is bad. So basically the first time ever this year with the wildfires.
