Definitely not a monoculture, but there's a few things that sharply contrast when compared to other countries. The biggest one I've noticed is strong individualism that sometimes manifests as rights and sometimes manifests as bootstraps. Another is using courts instead of regulating corporations (which they then avoid by binding arbitration etc) as well as a general litigiousness. Colonialism in definitely not unique to the US.
Some things that I think are unique to Usonions but not universal among them: mormons and evangelicals (though they're spreading), football, car culture (to the extent that it shapes laws, city planning, social life, employment, etc.).
I'm sure there's more but that's what's off the top of my head.

Basically a list of all the series I enjoyed enough to finish and would watch again.
I'm assuming this is a phone and you get most of your screentime at home. Start making it inconvenient for yourself. Set a really long password and disable biometrics. Uninstall interesting apps. If you can, block any sites taking up your time at a DNS level. Keep chargers away from places you can settle like couches or bed; use a very short cord or finding places you'd have to stand to charge it. Find replacements like books, physical things like legos or art. These are all just ways to start.
Eh, the beaver thing is really overblown. Considering how much labor and how many beavers would be involved in extracting castorum in sufficient quantities for industrial food production, don't expect it in anything you find at a grocery store in the last 40 years.
Alcohol is a great solvent for a lot of things. Tomatoes are another good example and why vodka sauce is a thing.
Depends a lot on the time of year, but Christmas is cookie season with buckeyes (peanut butter balls dipped incompletely in chocolate) and marzipan strawberries (marzipan and strawberry jello shaped into strawberries, rolled in red sugar, and decorated with plastic stems). Summer is a pie that involves a cream made of cool whip, sweetened condensed milk, and lemon juice covered in sour cherries in a sauce made from the liquid from the can they come in.
Late so the hucows can do the whole guns to butter thing. Or swords to cowshares.
