I guess it all depends on the OP definition of boring.
I play the Fried Liver attack which I think isn’t boring, but maybe the OP thinks it is.
I can't really use it because 9 times out of 10 your opponent knows the trap and prevents it
The Fried Liver Attack isn’t a trap.
It is a valid main line.
Black Side Players can seek to avoid it, but it doesn’t change anything.
The lines are still not boring and they are fun!
If you are a beginner, stay away from d4 or c4. I know, it seems restrictive but all the best advice is to learn the tactical principles and situations that arise from e4 openings first, before you start down the positional road of the queenside games.
Indeed, I've seen advice saying don't push d4 until you are rated 2000, or no longer a class player. That seems a little extreme, but the idea behind it is sound - if you can't make rating points with e4, you sure aren't going to make them with d4.
To your specific question, the Vienna Game is a sound alternative. So is the Scotch. Both of them have gambit variations if that's your thing, and they both are built around simple ideas and don't come saddled with a lot of theory. Plus the Vienna Game can inspire some exploration of the King's Gambit, an opening that doesn't get a love these days.
