If you always want to be first to the fight then you're going to need something that can survive a beating because you might be alone and outnumbered a lot. I think you'll want a DK or a Warden for that. Of the two I think Wardens are the most mobile. An orc Warden, for instance, is pretty darn fast with little effort.
The bad news is I think both of these are strongest when played with a hybrid lean towards magicka. Of the two, DK playstyle has the more melee feel to it I think.
Sounds like you want to be a dpsy tank, which I know DKs are known for. Warden and maybe Templar are also good ideas. In dungeons, you should never pull before the tank but if you’re a dpsy tank then can just queue as tank for normals most likely. Just use the morph of inner rage that increases your own damage against the target and maybe use chains. It’s fun chaining players in PvP too though I don’t know how well it’d actually work out.
If you want to run ahead and dictate the pace, tank is the best thing you can play, though. I don't think you should rush if someone is questing or the group isn't keeping up for some reason. On the other hand you can avoid delays by not using ZOS' "Are you ready?" feature. Just look at the group display in the top left corner and/or at the map to ascertain the group is present or that stragglers are almost there, then go. I've gotten compliments as a normal trial PUG tank while setting a brisk pace that way.Sounds like you want to be a dpsy tank, which I know DKs are known for.

I always queue as a dps, hate tanking. In pvp too, tanks don’t do much dps, just annoy and support.
Nightblade has a high skill ceiling. Picking off people, e.g. 1vXing, is a rather ambitious goal that is difficult at the best of times. You're typically working at the edge of a zerg, always making sure you have no one behind you. Clips on YouTube are invariably cherry-picked. Better to tune in to a good player on Twitch to see (a) how they build and play and (b) where they go on the map for favorable conditions. My suggestion would also be to play in Ravenwatch. A lot of newer players go there on PC EU. The competition in Ravenwatch is soft in my experience. You also won't run afoul of proc sets, such as Dark Convergence.I’m extremely impatient when it comes to combat meaning that in pvp and dungeons I’m always rushing to get to the next fight ahead of everyone. I don’t like waiting for the perfect opportunity, but rather creating it. I also don’t like too many pets or magicka builds. I’d rather have other players feel like there’s nowhere to run or hide.
See that’s what keeps happening to me as a nightblade-I rush into a group while cloaked, maybe take out somebody and then I get dumped. Or I’ll hang nearby, attempt to take someone out, get spotted, pulled out of cloak or caught. I want to be able to keep picking people off within a group because I would rather be in combat than running away/searching for an opportunity.
