YAY!!! Pörkölt is great, I love it though it’s not carnivore, good thing I am not that either just try to stay close 
We make the basic version in this household, meat, salt, onion, lots of paprika, fat, just like Mom did her stews.
Hungarians makes stew from nearly anyting (I wouldn’t touch tripe but tripe stew is very popular for some reason). I made stews while a vegetarian as well as there are meatless ones…
Of course it’s a bit individual what else put into a stew but the basic one is already great. But it’s hard to make beef stew without at least thinking of red wine, it’s a very common and popular variation, maybe it’s the norm, at least if a chef does it…? But it’s really good without extras. Sour cream is awesome with it, I don’t use it for every little bowl but it’s good indeed.
Of course I don’t eat vegetables with it, I eat everything with eggs. Other stews are fine alone but I find beef stew so rich (and expensive) even with sour cream that I use my trusted eggs in some form.
I only put tomatoes (well, puree) into egg stews but many people love to put it into nearly everything.
Bell peppers? Oh my. It’s not lecsó
I never use that but I am a savage as I barely put any into my lecsó (rip. since I tried carnivore and dropped vegetables almost completely, I don’t do veggie dishes. not like there isn’t a meaty version of it) and that dish is based on it normally… 
But yep, people use bell peppers too in dishes together with tomato (it’s usually not bell pepper but some other capsicum, I never know how to call that slimmer yellow one… but people loving hotness use some kind of hot pepper). Tomato goes with beef stew way better if you ask me and I still never would put any into it.
Yay for pörkölt! I don’t know about other folks’ stew, I only know ours and I am quite happy with it.
Use paprika according to taste. I thought I use a lot but it’s nowhere around the amount written in the recipe, that’s, like 8 times as much! I don’t really know a thing as too many paprika in a stew but my amount is totally enough and well, it’s a carby stuff and why to overuse it…
I use the most paprika (by FAR) for my egg stew, 30g (a bit more than 3 tablespoons, maybe?) for 30 eggs but that dish uses more than 2 liters of liquid too… For meat, it’s way less. And I think one should make a stew using way more than 1.5 pounds of meat, 2.5 kg (somewhere above 5 pounds) beef was a cute amount even if not much but we did it on open fire (that’s the best way) and anyway, each to their own. I made super quick pork stews using a tiny meat in a pan when I didn’t want to wait for 1-2 hours for my roast to get ready… 
I try not to get carried away even more. But I so, so love our stews
