Try multiple different openings. If some fit you well, play them more and learn more variants of them. There is no "best" opening: you need to use the opening that fits you the best.
What is the best opening to play as white?

Scotch game is good, but there is another debuts: Try Indian defence. 1.Nf3 Try Queen's gambit. 1. d4 d5 2.c4 You can also try King's gambit: 1. e4 e5 2.f4 But if black captures the f pawn, you shouldn't move d4 or d3, you should to move knight to f3 to avoid the check by Queen h4+

You are right, thanks.

I like to do openings where my pawns don't get smothered in the back, because the big issue I've struggled with is that I sometimes end up in a very cramped position with no way to push out. The Ponziani is good for this.

Well if you're a Scotch Game kind of guy, there are other aggressive ideas you can try. For instance, you can try the King's Gambit (1.e4 e5 2.f4). The Italian Game (1.e4 e5 2.Nf3 Nc6 3.Bc4) has some aggressive ideas but it requires a bit of study.

But dosen't the king's gambit weaken the kingside?
There's a reason you don't see it often past a certain point, and that's why. Moving the f-pawn isn't always bad, but typically it's not recommended unless you know what you're doing. The idea is often to attack quickly and effectively, which is something only skilled players know how to do well.
A rare example of where moving the f-pawn can be beneficial is the Vienna Gambit. Be aware, however, that it can backfire if your opponent knows the correct move to refute it. And since I know what it is, I'd hazard a guess that most people around our level do too.
