Not 100% word-for-word. I skim through most of them, (though that doesn't mean I'm not paying attention).
HoI4 feels a bit like a forgotten game. Wiki's a start, but there's substantial guides on specific aspects on youtube (watch out for obsolete ones). Some of the stuff there might help. You can sink a couple hundred hours into the game and overlook some mechanics.
It sounds like you had the Eurasian situation more or less sorted in one playthrough. If you want to try taking shots at the US try starting from Alaska, Greenland, or the Caribbean. Alternatively supply from Africa to the Panama Canal, then work/build your way up. Transport planes and air superiority are your friend, as well as the AI being so horrible at being America.

I tried using the defense sector today and that was pretty successful against the Germans. I feel that my units held better. Also, where can you see the supply limit for a province? It would help if I knew exactly how many men I can squeeze along the border tiles if I decide to micro it.
I don't know where exactly you're at in terms of drawing lines, orders, and giving units time for planning. But getting a handle on that, including like learning combat width (picking between 20/40 etc.) and what to do with the army types you start with before you get the XP to edit or add new division types so you use everything to its best capacity is pretty important. Germany again for example, some people at the line drawing stage will just make a big front against Poland and spear towards Warsaw. Lots of wasted, awkward momentum that could be used in capping the north and south victory points more quickly and getting a faster capitulation. Grab those, collapse on Warsaw. Pretty easy.
The whole fronts system does feel very unintuitive. I get that it's a complicated game, but things do sometimes seem needlessly so.
