Just some random ones off the top of my head…
The national parks (and some state parks like Valley of Fire)/natural monuments, (relative) freedom I mean you can buy guns and protest the president (for now), etc., unmatched innovation and creativity I mean Apple, Tesla, Space X, Walmart, Boeing, Microsoft, Amazon, Uber, Facebook, Google, Coca Cola, McDonalds uhhh like most big companies today, one thing I do like about American culture is the humor and that people are always making jokes — I guess you could say it doesn't take itself too seriously in some regard? It does have a supportive system for entrepreneurship.
NYC, LA, San Francisco, Las Vegas - arguably global cities
Its next to Canada and the Caribbean
Classic muscle cars
Moon landing/manhattan project/Denny Regrades, etc. - this country can seriously come together and make some big breakthroughs on massive projects
Cinema

(take the good with the bad)
Founding Fathers (yes, I'm sure thats controversy but whatever idc)
Strength of American passport
Relative standard of living globally especially if you're wealthy or have money
Relatively safe (for now)
The rugged untamed nature of this place…
The diversity -
look at NYC…
Etc.
Hmm… that's a toss up between the citizens, government and corporations.
Mmm… healthcare in America only works when you're healthy, public transportation (kind of city dependent but as a whole) sucks,
modern American cars (higher-end teslas models are debatable and not sure about Rivian), CA's political scene and the left coast, government corruption
Idk there are plenty of things the US is not the best at.
Too many to list…
