There can be many more the top 4 I mentioned is just a part of my own repetoire and preference 😁😁😁😁
Top 10 Chess Openings

Anything is fine if you study but it should be a sound opening (a sound opening are openings on which the eval bar is mainly from 0.00-0.005 according to magnus carlsen on magnus trainer app)
Anyway you should have a proper opening repertoire
And top 10 openings can matter on your interest
But the top 4 are ruy lopez, queens gambit and sicilian najdorf ,grunfeld as you learn lot of new chess concept and strategies when u learn openings which are very vast and sound
Top 4 are
bongcloud: ruy Lopez variation
bongcloud: queen gambit variation
bongcloud: Scillian variation
boncloud: gruntfled variation
is this what you meant?

My 10 years of defendable is what must work for you even regarless of fudamental theory like RL Marshal variation which marshall lives in many opening variations so much controlked and dynamic people would love to the game

1. Four Knights
2. Ruy Lopez
3. Kings Fianchetto
4. Queens Gambit Declined
5. Italian
6. Nimzo Indian
7. Center Game
8. Sicilian
9. Reti
10. Caro Kann

Top 10 e4 openings:
1. Najdorf Sicilian
2. Berlin Ruy Lopez
3. Marshall Ruy Lopez
4. Taimanov Sicilian
5. Anti-Marshall Ruy Lopez
6. Rossolimo Sicilian
7. Sveshnikov Sicilian

No Caro-Kann for a reason. I think 1. e4 c6?! is an inaccuracy in all but the Panov, Accelerated Panov, and Exchange Variations, and I won't have anything but the best variations in the top 10.
