One format, two searches
"Biodata format for boy" and "biodata format for girl" are searched separately, and most sites answer them with separate template galleries. They are the same document.
The sections are the same, the order is the same, and the design is the same. If you have seen a biodata you liked and it belonged to somebody of the other gender, you can use it exactly as it is.

What genuinely differs
Very little, and none of it is in the format. What differs is which optional rows a particular family expects to see, and that varies far more between families and communities than it does between a son's sheet and a daughter's.
Two households on the same street will want different rows. That is the real variable, and it is why the row list is yours to set rather than something a template should decide for you.
Rows that come up more often on one side
There are a few conventions, and it is more useful to name them plainly than to pretend they do not exist. Income and job stability get asked about a boy more often. Whether somebody intends to keep working after marriage gets asked about a girl more often.
Both are fair questions about either person, and plenty of families now ask both of both. Put in what you are comfortable answering; leave out what you are not. A row you left out is a question somebody asks on the phone, which is often the better place for it anyway.
The photograph does the same job either way
One clear picture of your face in good light. Not a studio portrait, not a group photo cropped down, not one taken from four feet below.
Every design here crops it to a circle, so whatever is at the corners of your picture will not survive the crop — frame it with the face centred and a little space above the head.
So what should you actually do differently?
Nothing, except be specific. The biodatas that read well are the ones where somebody wrote "assistant manager at a bank in Indore" instead of "working in a reputed organisation", and that is true regardless of who is writing it.
Pick a design you would be happy for a stranger to see, fill in the rows your family is actually asked about, and leave the rest empty.
