Honestly, i don't see the point of following the middle name anymore.
The ancient Chinese uses it as a way to find their ancestors or descendants and other family members related to them.
My family has stopped following this rule since my father's generation.

However, I understand ur predicament since my parents in law are still following this old school tradition.
Anyhow, you can just ask those feng shui master to give you a list of names to pick from.
Normally they will give you at least 3 to 4 options and they will explain why it's good.

I am banana too. Last time consulted my father in law for my son's name.
I didn't like it and I asked to change cause I don't want the name to haunt my son forever.

my daughter's middle name got 15 strokes. even my mom joked "next time, your daughter is going to complain why give her so many strokes to write"
