I have been in exactly the same situation than you and solved it this way:
I was in the library of a public music school and borrowed all(!) beginner method and beginner repertoire books they have had. One after the other, and then was listening by the accompanying CDs or by youtube systematically through them and picked my personal list of pieces. It was an intensive 3 month process in the end. With this list I was searching for my teacher requesting to build up my lessons based on my list, wherever possible.
Well, from the 10 books I found 30 pieces pleasing me. For my classes, we skipped 20 of them, because they didn´t add new value to the class but for learning to play have only been repeats of techniques already tought by other pieces, according to my teacher.
I first thought to anyway practice my other pieces, just for the joy of them, but found out that my skills improved and now I am already busy hunting for a new list of pieces at a slightly higher level. I guess it will go on and on like this
I by the way found out, that if finding a usual book with usually about 40 pieces in it, I usually like only 3 to 8 out of them. A book which gave me more than 5 hits I thus called a good book. So, I became used to accept that when purchasing my own beginners books I will have to pay the book´s price for finally receiving 5 to 8 songs of interest. This usually calculates to roughly 2 EUR per song of interest, which I still find accetable.
I´ll now try to again sell some of them, because I progressed in my skills from beginner to early intermediate. Once you reach that level you will find sooo much beautiful music, that I now have found a progressive book series Vol-1 to Vol-3 from which I like 35 out of 40 pieces in each book. Enough material for years to come! If my taste will not change
. Of course, I also have had to put quite some effort to find those, but it is completly worth the effort.
You know, there is so much bland classical music around for beginners up to early intermediate level, that you indeed have to search for some perls. But there are perls out out there, also for that level! So, don´t allow to get frustrated but push yourself to go to some libraries and start your search for your personal repertoire list now!
Sorry for not recommending you any pieces, as you expected to find it in an answering post to your question. Well, my answer is to make you understand that it is YOUR taste, and you will have to go for YOUR personal repertoire list YOUR way.
The latter - the way you are approaching your piano journey - might even be the most important step, because you will hear a lot of interpretations and will find that it truly makes a difference to what extend you also go through some boring parts of practicing technical excercises with the aim of nicely getting your own tone polished. Some recordings out there do nail the correct keys at the correct time pretty well, but are not musical, are not alive. You do not only have to learn to get the fingers correctly touching the keys, but you also have to learn to get you ears opened for critically analyzing HOW you are playing. Your success at the piano will be depend on building up a really effective feedback loop: from your mind forward to your fingers to the keys and from the sound back to the ears to the mind.
I am pretty sure that the step from intermediate to advanced level will then be to even move on to the following, something which already as a raw beginner is desirebale to at least try to find, although not systematically to become accomplished:
From your soul by your fingers to the keys and the sound by your ears back to your soul.
I am convinced that there are many people playing at highly advanced level, even being professionals already, but didn´t find to seemlessly connect their sould into such feedback loop by now. And there are some beginners and intermediates who will never be able to technically go for advanced pieces, but their music is so full of soul that it is unbeatable good! You read enough, go the library now, and all the best to you and your piano journey!
