At your level if you seriously want to improve your game I would recommend:
studying tactics till you reach 2500
watching a win at chess series with either Levy or a other chess creator of your choosing.
playing only 15-10 rapid and 5-5 blitz and nothing faster. And Analyse every game.
I’ve got levy’s courses and a few on Chessable, I love learning new opening and ideas but they are expensive and 90% of the lines learned don’t make it into my games as it requires reciprocated understanding I.E my opponent also has learned mainline theory.
If your like levy’s style and want to support his work then get the E4 NYStyle and Caro Kann and they are great for beginners- intermediate but I would recomend you shop arround aswell find what openings you find inspiring and suit your playing style. I personally love attacking chess so later moved from the solid caro Kann to the dynamic Sicilian D.
but right now the best value for your money at this stage would be just getting a Gold or Diamond Account here and grind it out in the puzzles
and watch a free win at chess series on YouTube to develop your thinking process and chess psychology! That along side tactics can not be understated enough!
you’ll begin to piece together solid understanding of opening middle and endgame principles with tactical board awareness, this alone will hike you up into the 4 digits in no time!
As for Learning an opening I would look at the Vienna as a starting point through levy but just the free YouTube video to begin with.
Through levy’s free content and puzzles study to 2500+ I went from 700-1200
after gaining a few courses and more puzzle study that pushed me up to 1500+
but it’s worth noting there are soo many content creators to chose from so I would shop arround find your favourite diet of chess instruction and entertainment and just enjoy the journey of learning 
best of Luck to you chief!
his courses are so bad you can't even give them away
