The United States could have just taken all of Mexico, but it didn’t. It paid for the land. The population of the western states was made up of Americans anyhow, less than a thousand Mexican citizens lived in those areas at the time.
The US took most of the land from Mexico that was worth taking. There’s little viable agricultural land south of Texas. Also, it put a lot of land in between Mexico and New Orleans, which is an incredibly important international port. With that secured, no foreign army would be able to threaten that port without major logistics challenges, much less fighting through the US Army and every local citizen with a gun.
The US grabbed what it wanted and let Mexico keep the scraps.
That is looking at it from today, not from how it was viewed then. The main reason Mexico was fine with selling was the massive desert that separated the two areas and the extremely violent native population that inhabited the region. That reason didn’t become peaceful until the 1920s.

How generous of you to call the natives American after the fact.
Someone: puts a gun to your head and says “I’ll give you $4 for your car”.
You: “This is a free and fair trade.”
That wasn’t the case, the Mexican government was run as an oligarchy. The United States threat was to threaten to turn over their lands to the public.
