What are some good openings do you recommend to play for a 500 rated player like me?

Do mean for white or black?
at the beginner level, U should prob stick to ..e5/ U might like the petroff defence , its pretty easy to learn/as you improve try different things. For instance at 1000 switch openings then again at 1400/
then finally at strong B-A level switch over to the sicilian defence
at that point you should have found something u like.
(also against d4 do the opening feature and find a line U like against the london system/ guys at your level love that opening fopr some reason.
later dudes

I wouldn’t recommend learning openings unless you are above 1000 but if you have to learn an opening, play the london system. Its super easy and fun, you can play it against almost anything and its actually what I play.

Opening’s honestly don’t matter until you’re above 1000, but I’d recommend the London System, Pirc Defense, and the King’s Indian Attack if you really want to play one.

London system is actually very bad for beginner chess development. It's easy but quite dry and unambitious. It can teach bad habits as you are only learning to play on autopilot and not challenge the opponent in the opening.
Ruy Lopez, Queen's Gambit, Italian (particularly some gambit lines) or Scotch are all way better and more fun.

500 rated players do not need openings. They need to a) avoid blunders b) be able to pick the free material.

I am working into improving my openings, for when I used game review, I was better in the midgame than the opening. Is there any openings you recommend?
Here's a neat little repertoire for you. I'll give my TL;DR. Closed Sicilian, Kramnik Sicilian, and Canal Attack Sicilian, Advance Tal Caro-Kann, Classical/Poisoned Pawn Winawer and Boleslavsky Steinitz, Exchange Scotch, Exchange Philidor, Classical Petrov, and Mieses Kotrc Mainline Scandinavian.
Against Pirc, Owen's, English, and Modern, just play e4 d4 c4 Nc3 Nf3 Be3 Be2 Qd2 0-0-0. If they play those openings they won't bother you much for like 10 moves.

The idea that beginners don't need to learn openings is so completely wrong. Openings are important at all levels. Improving your opening play is improving at the game.
You can say "the opening moves don't matter, just play anything". You have no idea how often lower rated players play this.
And fall for this sacrifice.
Some people who never learned anything about openings end up playing stuff like 1. e3 e5 2. f3 because they don't know any better. A lower rated player in another thread was explaining how this is a good opening for white that he made up.

Main line Open Sicilian is way better. If you are going to play the Poisoned Pawn Winawer then you may as well play the Classical Bg5 Najdorf or Fischer-Sozin Attack.
Fischer-Sozin Attack can be a dangerous weapon. It's a very nice choice to start with for the attacking player and can be played against 3 different Sicilians.

Not for a 500. The Poisoned Pawn Winawer plans are much simpler for White, whereas the Mainline Najdorf plans are much less clear.
I'd actually recommend the Sozin for 1400s picking up the Sicilian, but OP isn't 1400 yet, and the Closed, Kramnik, and Canal Attacks will be very very useful if they decide to change repertoires later. The Closed is similar to KID, Kramnik is similar to Tarrasch, Canal Attack is similar to Ruy Lopez.
Mainline Najdorf is similar only to Mainline Najdorf, there's nothing else quite like it, which is a good thing but also a bad thing due to the unique complexity.

So you folk are suggesting that I should check out Fischer Sozin if I ever switch into Open Sicillian from Morra?

Yes absolutely. It's a very interesting and fun variation, and it isn't too common at lower levels, so you're likely to catch opponents by surprise. It's also much much more solid than the Morra.

I agree with the fact that it’s dry, but it helps teach good principles, and can be a good base off of which you can learn other openings (for instance, the Trompowsky). I think the Italian Game is pretty good for beginners, and the Queen’s Gambit is also great. I do think the best beginner repertoire would be the Caro Kann, Italian, Pirc, Queen’s Gambit, London, and King’s Indian Attack. The Owen’s Defense, Trompowsky, and a Scandinavian are better for more advanced beginners.

The issue with that repertoire is that aside from the Queen's Gambit, all of those are very complex positional, waiting, defensive openings, and beginners usually are much more suited for attacking, not defending. I'd argue that that's actually a fantastic repertoire for 1100-1400 players, (advanced beginners) and Owens/Trompowsky/Scandi is a better repertoire below 1100 (beginners).

You do make a very excellent point - I teach chess classes, and for the most part, my students love the Owens/Trompowsky/Scandi as their main repertoire, with some other stuff on the side, like the London, KIA, and Queen’s Gambit.
