How I chose my opening repertoire

Ever since I started chess, I've almost exclusively played 1.e4, the King's Pawn opening. Recently, I've branched out into playing the Zukertort (1.Nf3) and the Queen's Pawn (1.d4) with similar plans. My struggle has been the fact that my repertoire of cheap tricks as White (fried liver, b3 Sicilian and French, a borderline losing gambit against the caro, the Monkey's Bum setup against the Pirc) and Black (Blackburne-Scandinavian with c6-, Englund Gambit, Anglo-Scandinavian Defense, Ross Gambit) works against most players sub-2000 rated, and most players below 2200 in blitz and bullet. The problem I was facing is, how do I beat stronger players, like the ones I face in the Lichess Bundesliga, by playing these openings. The answer was, I don't. In fact, my best wins in Liga happened when I switched openings. But to what?
My answer, as it turns out, came when I started listening to my friends on the Lichess discord. At first, their suggestions faced opposition. The Sicilian was too complicated, the Grunfeld was too annoying, the semi-slav was too slow. However, as I continued to struggle in the opening, I began pursuing these opening ideas, watching YouTube videos, and studying lines.

This is the 4 Knights Sicilian I mentioned earlier.

For me, there are 5 criteria to consider when selecting openings for a repertoire:
1. How common is the opening? How often can you play it?
2. How well known are the best plans of the opening? Will most people play the best moves against you?
3. How well do you understand the ideas of the various middlegames from the opening? Do you know what to do when the opening ends?
4. Do you enjoy playing the opening? Playing an opening that you hate yields worse results.
5. How good, objectively, is the opening? No point in playing an opening that loses by force.

There are other criteria, such as if you are making a blitz repertoire you might want to include more traps, or a classical repertoire might include some sidelines.
With that in mind, I have selected for White: d4 with a Catalan setup, for Black: 4 knights Sicilian, Grunfeld, Symmetrical English.
As a blitz repertoire, I will choose between d4 and my e4 blitz repertoire of traps and tricks.
