I haven't really had to adjust the climate controls in my current car since I bought it, aside from pressing the defrost button a few times. During that time outside temperatures have ranged from 15F to 110F, and my car is always comfortable inside. Even the heated steering wheel and heated seats are automatic, I haven't had to manually control those either. Automatic climate control has worked very well for me across 4 different models of cars ranging from a 2000 Honda Accord, a 2012 Ford Focus, a 2017 Hyundai Santa Fe, and a 2021 Mustang Mache E. All of them pretty much never required me to adjust it day to day, and I would go weeks to months without needing to do anything.
Given that you're talking about only being able to set the temperature selector down to 65, it sounds like you're doing automatic climate control wrong. You're going to have a bad experience if you're always setting it to max cold or max heat instead of just picking a comfortable temperature in the middle and letting the car get to that temp. Sure, it'll take a minute or two before it starts blowing air, because usually the AC needs to really start cranking before its doing anything or it takes a bit for the heater core to warm. During that time you're not really doing much blowing around the air, in fact you might make the experience in the car worse blowing non-conditioned air around.
Just like in your house, setting your AC unit to 60F isn't going to make your AC unit run harder. Do you go to your home thermostat and drag it all the way one way when you're warm, then drag it all the way to the other direction when you're cold? No, you set it for a comfortable temperature and let the system hold it there.
