still not sure what you think is missing.
You can write your own UDFs.
There are some built-in functions which can assist you in things like STD.
You are asking if FB supports aggregate functions. The answer is yes.
It supports UDFs of your own making if the built-in ones are insufficient.

if you are, on the other hand, asking if FB supports whatever function/UDF
library you are currently using in SQLite, then I can't help since I don't
know what they are.
