i’m trying to find an opening
You are rated 400. Not time to be worrying about openings. You need to learn the following first:
1) How not to hang pieces
2) Endings
3) Tactics
4) Strategy
5) Calculation
Only then can you maybe start thinking about openings.
Benko Gambit Though played on occasion (in a slightly different form) in the 1930s, this gambit was not really appreciated as a positional weapon until Grandmaster Pal Benko's employment of it in the early 1970s (later champions of this line were American Grand- masters Walter Browne and John Fedorowicz). The sacrifice on move three (after 1.d4 Nf6 2.c4 c5 3.d5 b5) seems odd at first sight, but Black happily parts with a pawn so that he can open the a-file and b-file for his Rooks. This will lead to a powerful and long lasting queenside initiative, and not all White players are happy to defend from such an early juncture.
Openings are interesting. I started looking at some of them. The problem with them is that studying them doesn't mean that's how the other guy is going to respond to your opening. They at least give you ideas. I think center control, piece development (without blocking yourself in) and being ready to punish the opponent for bringing out their queen too early is more important than "openings" per se. Knowing what the "traps" are for your opponent's opening moves is important though.
Attacking really isn't your priority right now.
Here's an analogy to help explain what I mean:
Initiating a " fist fight" with out knowing how to defend yourself is a bad decision.
Here is a simple opening that you can start playing while you learn how to play. it works for both white and black positions.
white: 1.Nf3,... 2.g3,... 3.Bg2,... 4.0-0 then decide on which center pawn you want to move and develop your other pieces.
black: same thing 1.Nf6,... 2.g6,... 3.Bg7,... 4.0-0,...
Now you can concentrate on middle game and tactics.
I'm a beginner and I've been trying out a bunch of different openings, and the thing is that they are generally situationally useful ONLY. A certain opening can be brilliant in one case and disastrous in another. So unless you have studied a lot, you just end up putting yourself in bad situations quite often. So I stopped messing with them for now, and what I have been doing is opening with e4 as white, countering e4 with Caro-Kann as black, and going d5 if they go d4. If they open with a knight, I take the middle square that their knight isn't attacking. Early aggression is fun, but it puts you very much behind the 8 ball when it doesn't pay off, because you aren't developing your pieces.

sounds like you are learning and improving! keep studying and playing to the best of your ability and you will do fine.
You want an attacking line?
