Others ways to say "I wish you the best in your decision"

I’m writing a business letter. Wondering if there are other ways to say “I wish you the best in your decision” (already used it in a recent letter to the same person).

Found “I wish you well in your decision.”

Also found the following somewhat related topics. Interesting, but no cigar:

"Best of luck" or "Best luck"?

Wishing someone that something goes easily for them

What is the neutral way of telling someone to "do whatever you want"?

Grateful for your help.
