The London System is the usual go-to for first opening as white, as it allows you to play basically the same set of moves for most games, especially at low ratings where the opponent doesn't know how to counter it specifically, getting a solid, dependable order of pieces. I got to 1000 relying on the London before moving on to other openings.
For black, the Caro Kann against e4 allows for (relatively) intuitive moves and (relatively) limited variations. Against d4 you will often see the Queen's Gambit, and for that I like the Slav defense followed by dxc4 and b4 to create a well-defended pawn formation on the queen's side.
Anyway, for your first opening, the London System is the way to go for many players, and there are plenty of free videos online that will teach you enough to play it without having to memorize specific lines.
At the moment I am sort of freestyling the openings and I am doing okay, sometimes, but whenever I try to learn a chess opening I seem to pick the ones with like a million variations and it's just too much to remember all.
What's a nice, beginner friendly opening that you would recommend? I only play chess since a few weeks, so very low elo.
