All of those sound more difficult than their grade would lead you to believe, and all are easily learned:
Granados: Dedication (op. 1 no. 1) – Just one page long, beautiful lyrical melody - grade 4.
Shostakovitch: Schirmer publishes a great collection of Shostakovitch easier pieces called “Easy Pieces for the Piano”. Excellent material sounding far more difficult than it actually is. My favourites are Lyrical waltz, Lullaby and Spanish dance. Try also his collection “Dances of the dolls” (My favourites are “Hurdy Gurdy” and “Dance”) – grade 4 – 7
Richard Rodney Bennet – Diversions (7 pieces some very easy. My favourite in no.2 which is slightly reminiscent of Debussy’s Arabesque no. 1) – grade 5
Rheinhold Gliere: Song op. 34 no. 9 (beautiful piece in modern counterpoint, not as difficult as it looks) – grade 5
Jacques Ibert: The sewing machine –very patternend and repetitive. Great fun (it imitates the noise of a sewing machine). Not much of a tune, but very percussive. Grade 4
Beethoven – Six Ecossaises – Rhythmic and uplifting, yet incredibly easy. Kissin often plays it (superbly) as an encore. Grade 5
Scarlatti sonata k32 – just one page long, very easy (easier the Fur Elise, but far superior musically) lyrical and reflective (baroque though, not romantic – but don’t dismiss the Baroque period: it had a lot in common with the Romantic period). Grade 3
Erik Satie – Gymnopedie no. 1 – Two pages long, but effectively one page long, since the second page is an almost exact repeat of the first. Haunting melody over a chordal accompaniment. Again easier that Fur Elise but musically superior. Gymnopedies no. 2 and no 3 are equally beautiful, not so overplayed and equally easy. You can also try his Gnossiene no. 4 – the easiest and (imo) the most beautiful of the six. Grade 4 - 6
Edward Mac Dowell – To a wild rose – Achingly beautiful piece slow and romantic. Grade 4
Amy Beach – Secrets – This is my favourite piece in her Children’s Carnival op. 25. Very easy, yet the musicianship is so superior that one easily forgets this was originally a children’s piece. Broken chords divided between both hands, so that the hands are never together, smooth and flowing. Just beautiful. Grade 3
Adolf Jensen – Lied – Another hauntingly beautiful piece (just two pages long) from an unjustly neglected composer. Grade 5
Jacques Duphly – A wonderful, almost unknown baroque composer. You can get the scores of his pieces here:
https://jacques.duphly.free.fr/All four books are available for free, and each piece comes with a 20 second MP3 clip so that you have an idea of what the music is like.
Here are my favorites (so far):
The most beautiful Rondeau (2) in book 1
La Victoire , La Felix in book 2
La de Villeneuve, La Forqueray and the amazing Chaconne in book 3
La de Vaucanson , La de Drummond, and the superb La Pothouin in book 4
(Grades 4 – 6)

I hope this helps.
By the way, let me second xvimbi. I am also curious on how and why people end up in this sort of situation.
Best wishes,
