You will normally see a cabin altitude of between 5000 and 6900 ft depending on cruising altitude and what equipment you are flying in.
Most people can easily tolerate an equivalent effective cabin altitude of 8000 ft. In general, only people with compromised lung or heart function should worry about going above 5000 ft.
I have found your numbers to be exactly correct. I have an ear condition that is possibly affected by cabin pressure. I bought a pressure gauge to measure pressure in flight. Most of the time, the pressure is taken to about 24-25 in-Hg, or about 7000 ft compared to atmospheric pressure at sea level.
As for simulating the cabin pressure, Denver at 5000 ft. is close as is Salt Lake City. Leave either one and go about 3000 ft up in the mountains and you have it. Park City, Utah, is 7000 ft and a beautiful place to visit. Mexico city is closer to 8000 ft and Toluca (about an hour away) is near 9000 ft.
