What you are describing is the classic application for which the wirenut
was designed to solve.
Namely, the joining of a solid conductor (Romex) and a stranded pigtail
(the lighting fixture).
It is not a particularly good long term connection; however, there are
some conditions in this application that minimize future problems.
1) There is very little chance of vibration impacting the wirenut
2) The load is probably 600 watts or less so long term heat build up as
a result of a high resistance connection is minimized.
About the only possible alternate to a wirenut that is economically
viable would be a butt splice connector which would be totally dependent
on being able to make a proper mechanical crimp on a solid conductor,
something I'm not qualified to comment on, but would refer to the splice
