The lack of a main.cf file is a choice made by the O/S distribution.
When installing the package, you must have opted for "no configuration",
rather than a specific configuration (local only, inbound server, ...).
The upstream "make install", when building Postfix from source does
create a main.cf file.
So your issue is with Ubuntu/Debian, not Postfix.
That said, yes, create a "main.cf" file that meets your needs. You can
start with an empty file, or a copy of "main.cf.proto".
Personally, I always start with empty files, but I'm already quite
familiar with the options I want to set, and prefer to avoid the clutter
of all the comments, that for me obscure the big picture. For you the
comment blocks for each of the common settings may be more helpful.
