The question is not what style, but what instructor. All traditional styles have everything needed (except espionage, which you don't need). The problem is that many no longer teach all of their style. In order to find a school that does requires some research. Research should co0nsider each school / instructor not the style. Some instructor know and teach the whole thing while many don't know their whole style and don't teach it all.

All martial arts cover this material.

So I could just list the arts, but they all comply with that.

Only the sports divide this stuff. The reality of martial art prevents such division. In a sport you know what the opponent will do in advance, according to the rules. In reality, you never know what an assailant will try to do.

Martial art by definition must cover it all to be a martial art.

edit:

pugpaws2 is very correct. All true martial arts contain all elements. Many instructors either do not know all their art, or disregard teaching parts of it. I have even heard karate called a "stand-up" art, or a "striking art". Odd that, as karate began as a grappling art in Okinawa, and added very potent strikes as the Chinese influenced the art.

Most of the traditional martial martial arts will do this. But you do not get any espionage. That is not martial arts. In many TMA you will get a very limited amount of the culture. If you want to learn about culture you should take some classes.

Every single martial art contains everything you need to defend yourself. As long as it is taught correctly, every art in existence contains everything you will ever need to defend yourself, including all of the things that you mentioned (except espionage, because you don't need to infiltrate buildings and eliminate targets in real life).

It depends entirely on the instructor as to whether or not you learn everything in a certain style. The style does not matter, the instructor does, so seek out a good instructor regardless of the style and you will be all set as long as you train right.

Now go forth, and seek put a good instructor.

None are like that. You are delusional about what martial arts is and what it will give you. You have watched too many movies and you have this picture in your head that doesn't match reality.

Ninjutsu is BS and it doesn't exist. Knife and weapon defense is crap in about 90% of all dojos. They teach something that does not match reality and that is quite frankly dangerous. You have these stupid kids running around thinking they can disarm someone who points a gun or a knife at them but none of them have trained to disarm someone who is resisting them. Those are two very different things. Fighting someone who is resisting you and fighting someone who just plays along.

The most well rounded art out these is probably MMA. It deals with all forms of hand to hand combat. Stand up, clinch and ground. But there is no weapons involved. But if someone comes at you with a gun or a knife then never trust your training. Just run.

You have a couple options. Either join MMA which most often consists of muay thai, bjj, wrestling and boxing. Or take up the individual martial arts. Maybe kyokushin with judo or muay thai with bjj.

I want a powerful, well rounded art that incorperates striking (punching, kicking, etc) with grappling and joint locks and any other various other things like weapon use, espionage (like ninjutsu) and any other cool skill. Also I want an art that has will help educate me of a foreign culture though that is not needed.

Thanks
