What openings are recommended to play as white/black for new players

Sure. Keep an eye on your opp, don't get tunnel vision thinking about just your own plans.

Should I play the same opening repeatedly to learn it well or try different things?

Depends on what your own goals are.

If you are just trying to beat the next low-ranking player that you face and gain a few rating points, then always playing the same openings will improve your win rate a bit, because of home-ground advantage... you will know the line better than your inexperienced opponent.

But that style of play means that you will learn rather slowly, because you are always playing familiar types of positions and are not being exposed to new challenges or new ideas.

If instead you want to learn and improve as fast as possible, then playing a wider variety of openings and facing a wider range of challenges will certainly speed up your progress. But it will mean - temporarily at least - a lower rating, since you will probably be playing many of these games on your opponent's home turf.

As white start with 1. e4, and as black start with 1... e5. I'd recommend aiming for the Italian. 
After some time try out 1. d4 > 2. c4. Try to play the Queens Gambit. 
Your goal in the beginning should be to learn tactics and classical chess principles, you can branch out later.

I started with e4, finally tried d4... I prefer d4. But I do like my opponents to play e4.

It might be weird, but I really enjoy learning new openings and trying them out, but I get advised to not be doing that. And yes, it has often been a disaster or would be if I worried about my rating. I have a good win/loss ratio as White, the opposite as Black because I keep trying different ideas. Also, even though I really like the Rousseau and the Budapest, Gambits.... I'm not having much success with them. I need to either go back to playing kind of a mirror image Jobava London or find something new (just no King's Indian please).

The people who advise you not to learn openings all learned openings when they were starting out. They're peddling a false pretense based on abstract philosophizing that has no grounding in reality. What they're not considering is that, through the process of learning an opening, you learn all kinds of things that you do not learn otherwise - different patterns, ideas about positional chess, different middlegame plans, etc.. And where else are you gonna learn these things? If you just play chess... you'll get experience, but you will do that regardless. And it doesn't even take long to get an overview of an opening, it's like a few hanging pawns videos worth of time. Heck, your tactics do improve after you play an opening for a while, since there are common tactics that arise. And even moving pieces around the board as you explore an opening helps with visualization.

ty, that strikes a chord with me

I didn't learn my openings by trying to memorize list of variations, or by watching videos.

I learned them by playing over games by the old masters, from Morphy to Alekhine.

That meant that my openings were solid but not entirely up-to-date - not necessarily a bad thing.

I respect that, and thanks for sharing that.

Play Italian!!!!

12. How to choose your opening

it depends on the person who plays the opening because all openings have disadvantages and advantages. For example we get the Italian game and it has the advantage of being reasonably easy, and is an opening that gives you different positions after it so that you can practice many positions, but the disadvantages are that the middlegames can be hard to play at times, can bait players to just doing the fried liver and not really learning, and at intermediate almost all players are prepared against it. What I am saying is that if you like the advantages and don’t mind the disadvantages much then the opening might be a good one for you and don’t forget about the style of the opening and if it’s not your style like for example positional style then it’s not for you unless there is another line that can’t go to your not preferred line in any way. I will say more examples of disadvantages and advantages. Advantage examples: easy to play middlegame and opening, is a system opening, gives different after opening positions to practice other positions, matches your style, and not baiting players into just trying to trap players. For disadvantages you have hard to play midgame and opening, doesn’t match your style, leads many players into just trapping people, and not a system opening.
