Middle name suggestions for a rather... unique first name?

My best friend just found out the gender of her baby is going to be a girl and she’s ecstatic.
For about as long as I’ve known her she has always told me that if she has a baby girl, her name would be

Sachiel

Pronounced: Sah-che-el

The name is based off the archangel Sachiel, the ruler of [name_m]Jupiter[/name_m] and presider over the zodiacal sign Sagittarius.
She is due in [name_u]December[/name_u] so the baby will most likely be Sag, a coincidence that she thinks isn’t so much of a coincidence lol.

My friend is into religious and occult studies so this name is pretty much dead set.

[/b]She’s given me the honor of choosing a middle name so I’d like to ask you guys if you have any ideas on a name that would flow well?

Huh. Interesting!

Sachiel [name_f]Allegra[/name_f]
Sachiel [name_f]Victoria[/name_f]
Sachiel [name_f]Celestia[/name_f]
Sachiel [name_f]Pandora[/name_f]
Sachiel [name_f]Circe[/name_f]
Sachiel [name_f]Astrid[/name_f]
Sachiel [name_f]Gaia[/name_f]
Sachiel [name_f]Evangeline[/name_f]
Sachiel [name_f]Hazel[/name_f]
Sachiel [name_f]Jade[/name_f]
Sachiel [name_f]Luna[/name_f]
Sachiel [name_u]Raven[/name_u]
Sachiel [name_f]Willow[/name_f]

Sachiel [name_f]Amira[/name_f]
Sachiel [name_u]Juniper[/name_u] or [name_f]Juno[/name_f]
Sachiel [name_u]Valentine[/name_u]
Sachiel [name_f]Miriam[/name_f]
Sachiel [name_f]Guinevere[/name_f]
Sachiel [name_f]Zora[/name_f]

It reminds me to [name_f]Sachi[/name_f], which means happiness. Sachiel is surely unique and interesting.

I’d give her something solid and classic, or at least more familiar.
Sachiel [name_f]Amelia[/name_f]
Sachiel [name_f]Catherine[/name_f]
Sachiel [name_f]Genevieve[/name_f]
Sachiel [name_f]Aurora[/name_f] - my favourite. It’s sweet, familiar and continue the celestial theme for a bit.
Sachiel [name_f]Caroline[/name_f]
Sachiel [name_f]Calliope[/name_f]
Sachiel [name_f]Juliet[/name_f]
Sachiel [name_f]Rowena[/name_f]
Sachiel [name_f]Emmeline[/name_f]
Sachiel [name_f]Juno[/name_f]
Sachiel [name_f]Astrid[/name_f]

[name_u]Love[/name_u] the suggestion of Sachiel [name_f]Aurora[/name_f]!

A few other names that flow and have nice meanings:

Sachiel [name_f]Electra[/name_f] (seems appropriate for a fire sign)
Sachiel [name_f]Felicity[/name_f]
Sachiel [name_f]Irene[/name_f]
Sachiel [name_f]Kerensa[/name_f] (means “love” in Cornish—I know a [name_f]Kerensa[/name_f] who’s bright and bubbly)
