Looking for an advanced opening weapon for white

Title. I've been playing the Vienna for a while, and initially, it worked. But now that I'm around the 2200 rating mark, the surprise factor is much less effective and my opponents usually figure out how to make it from the opening with a decent position. Not that an opening is supposed to give me a winning advantage, but it's just that I'm not a huge fan of the resulting positions. I've also been trying the KIA as white but I'm not a huge fan of it either, although I love the KID as black, because I'm not usually a fan of system openings. I just don't imagine myself going for these two openings in a serious tournament, and in my online games I've been enjoying having the black pieces way more than white. Hence why I'm looking for a reliable weapon for white, that's ideally not too theory heavy, since I'm a casual and don't intend to study chess very seriously. But I guess at this level there is no escaping opening theory, so I am willing to learn some theory.
Opening I've been considering are:

The Ruy Lopez with d3 (instead of the theory-packed mainline).
The English (But I find the symmetrical lines rather boring and unattractive).
The Reti, that can result in many types of position, including Benko/Benoni style positions that I don't mind. But it seems like I need to know way too many openings it might transpose to in order to play it so I'm a bit hesitant, although I'm really attracted to it, and I'm not sure how I would study it.

The Catalan, but this one scares me a little bit with how often it's played at the GM level. 

What I play as black: French vs 1.e4, and KID vs 1.d4.

Also, I'd be glad if anyone can suggest free resources for openings, or just describe how they study openings.
Thanks.

I've started playing the Jobava London in 2022 and I'm enjoying it a lot.
It's very different from the boring London we all hate so much.
In many of the variations White goes straight for the king's throat with a g4 attack.
The opening is kind of new but there are some good resources on it.
As far as I know there are Chessable courses of Simon Williams, Hans Niemann and James Canty, aswell as a .pgn file sold by Naroditsky/Bortnyk.
The opening is played by many great players , also in classical time control.
I don't know any free resources other than Youtube or blogs.
