I have never heard of Wormald Variation.
What does it look like?
You never heard of it because it is actually called the Worrall Attack (5.Qe2 in the Ruy Lopez with 3...a6)
Italian requires the medium level of theory.
Ruy Lopez takes 10 years to study
London system is a systematic opening, which means if you premove it, you’ll likely lose all your pieces.

Yeah, I have heard of the Worrall Attack because I remember Paul Keres playing it in a game if I’m not mistaken.
Not sure if Wormald & Worrall transpose into each other or not.
I think the W. Attack is 6.Qe2.
The main move is 6.Re1 defending e4 pawn.
The Worrall Attack defends the pawn with the Queen 6.Qe2 instead of the Rook.
It looks like the Wormald Variation is trying to avoid the Open Ruy Lopez with 5.Qe2.
Most people don’t defend the e4 pawn at that juncture because it’s not really hanging.
If Black tries to take it, Black often has to give the pawn back to avoid getting into trouble.
Its still a playable position for Black the Open - Ruy Lopez. Not extremely popular as it use to be.
I have heard of the Anderson variation which plays 5.d3 to avoid Open Ruy Lopez.
So I am guessing the Wormald has to be trying to play in a similar spirit.
The d4 square is a lot weaker for sure.

US master Thomas Herbert Worrall was a well-known and fairly strong chessplayer.
But there was also the less known British player Robert Bownas Wormald (he died at just 42) which apparently gave his name to the variation.
Funnily enough, British GM Nigel Davies names the line after Worrall at his chesspublishing surveys. There are no records on Worrall playing it.
Here is the first recorded game on the variation. White played horribly, and lost.
I teach beginners to play the ruy Lopez exchange variation - it's a great opening because you have such an easy plan as white which you can continue the entire game, swap off all the pieces and win the endgame
The Ruy Lopez is a good option for beginners.
I love taking opinions from 100 elos
I'm too! 
I’m talking about if you want to study all the variations
I think Ruy Lopez and Italian are equally good since the many variations
For me (not speaking to beginners) the italian is the easy choice here.
- london is just boring / lame. I would recommend the Jobava though
- Ruy Lopez is too theoretical and you have to deal with the Berlin.
- exchange ruy lopez or other equalish ruy sidelines... okay but if I'm gonna play an equalish position to avoid theory I'd rather play the vienna game, both the g3 and Bc4 variants are quite good... this changes the nature of the position more radically... four knights spanish is another option which has alot of transpositional value.
