Normally I would suggest "O Mio Babbino Caro" from "Gianni Schicchi" , but we know how that's unfortunately become overdone and trite.
I'll give you arias, as well as some art songs to consider. With art songs, it's perfectly acceptable to transpose them into any key you want that will best showcase your own voice.
Most of what I will suggest may not necessarily show of your high E, but tends to be mostly in the upper part of the treble staff which for you would really show off a high range, but still be low enough that the notes will just flow out like honey. (Well, maybe not honey since honey pours out kind of slow--but I mean it should be warm and beautiful if you are a lyric soprano). A couple will be challenging in so much as the required breath control to sing it.
"The Sun's Whose Rays Are All Ablaze" from Gilbert and Sullivan's operetta "The Mikado"
"Poor Wandering One" from "Pirates of Penzance" (there is a section for a cadenza where you can certainly insert whatever notes you want)
"Quando m'en vo" (Musetta's waltz) from "La Boheme")
"Depuis le jour" from "Louise"
"Und ob die Wolke sie verhulle" from "Der Freischutz"
"The Trees on the Mountain" from "Susannah"
"Vilja" from "The Merry Widow"
"Song of the Moon" "Rusalka" (if you can actually sing it in Czech, so much the better)
"Marietta's Lied" from "Die Tote Stadt"
"Je dis que rien ne m'epouvante" from "Carmen"
You might definitely consider some Mozart arias---this is a concert piece:
"Vorrei spiegarvi, oh Dio!"
Other songs:
"Vocalise" by Rachmaninoff or "Bachianas Brasileriras No.5" by Villa-Lobos
(gorgeous for high sopranos, but not easy)
"Apres un reve" Faure
"Ave Maria" Vavilov (which he attributed to Caccini, so this is actually referred as Caccini's "Ave Maria")--available in different keys and arrangements
"L'abbandono" Bellini
"Du Bist die Ruh" Schubert
"Nacht und Traume" Schubert
"Nina" attributed to Pergolesi (a few runs, but nothing outrageous--very short and sweet)
"Mattinata" Leoncavallo
"Widmung" Schumann
"Bist du bei mir" (try it in Ebmajor)-Bach
"Adelaide" Beethoven
"Music for a While" Purcell
"I Know that My Redeemer Liveth" Handel (from "Messiah")
Without knowing more about what level (how long have you been taking voice, and is this a high school senior recital or a college one?)
Have your voice instructor help you select songs that might work for you .
There is a LOT of music you can pick from, so I can see why you might have trouble making up your mind among so many choices.
