Obscure intermediate piano pieces to learn

[killsaved42]

I'm an intermediate piano learner (having recently played pieces such as the Chopin nocturnes Op 9 No 2 and the Posthumous C sharp minor nocturne, as well as Arabesque no 1, Fantasie Impromptu and some of the WTC) and my teacher has recommended I play some obscure piano pieces (due to the nature of my schooling system) for my course, I would like some recommendations of pieces preferably late romantic, impressionist or 20th century. (I have attempted Godowsky's Java suite but found that the polyphony was too difficult for me to properly express, and it just sounded like a pentatonic mess).
Any and all help is appreciated

It's always hard to know who counts as obscure, but compared to the two Chopin Nocturnes you mentioned, Leos Janacek's "On an Overgrown Path," is on the obscure side. A suite of short 20th century sketches with lots of different moods and textures.

Some of the pieces from Villa-Lobos' "A Role Do Bebé" might be good.
Takashi Yoshimatsu "Pleiades Dances" are very nice. You could make a selection of those or the "Piano Folio… to a disappeared Pleiad"
I also really like Norman Dello Joio's piano music. Especially the Capriccio on the Interval of a second but that probably a little more on the advanced side.

Mompou's Musica Callada is simple but evocative harmonically. It's definitely not the most exciting works but still one of my favorites from the 20th Century. Sorry for the video quality.

Are you interested in obscure pieces from well-known composers or should both be obscure?

Preferably obsucre composers but either works really Just needs to be somethings that isnt already played to bits, a short 5 min peice and around the right difficulty (I know its a bit difficult to define obscure, ive heard some people call paganini or scarlatti obscure while other go so far as to say the likes of godowsky or  katchaturian arent, so its really up to your discretion)

Maybe give Julius Röntgen's piano music a try.  He's Belgian/German, b. 1855, d. 1932.  He was an acquaintance of Brahms and Grieg, among others, and composed over 600 works, but I've never encountered a live performance of any of his works.  I believe IMSLP has most of his piano music.  I'm currently working on a fine piano piece of his called "Sérénade Mélancholic" and is not too difficult but about the length you are looking for.  But he wrote a slew of other piano music, so there's a lot to choose from.  Recordings of his piano music are available on the streaming services.  ...There are many B-C grade romantic period composers, most of whom aren't worth the bother, but I think Röntgen is a B+ and deserves to be heard.

The Fauré Nocturne no 11 in F-sharp Minor, Op. 104 No. 1 might be up your alley. It's not easy if you are intermediate but the challenges are more of a voicing, legato, interpretation nature rather than brute technique.

Enrique Granados has some nice intermediate pieces.

Andaluza (Spanish Dance No. 5)

Another nice piece but a little bit more difficult:  Quejas o' maja y el ruisenor from the opera Goyescas (Laments or the Maiden and the Nightingale)
