is there a built in way to get first match or nil for a character from string.

i can get a first character like this

'word'.match('o').to_s

but if there is no match it gives "" not nil

Use String#[match_str]:

If a match_str is given, that string is returned if it occurs in the string.

Returns nil if (...) the match string cannot be found.

'word'['o'] #=> 'o'
'word'['q'] #=> nil

The [] method is very versatile, you can also pass a regular expression or indices in different ways.
