Neither the FAA nor your future employer will likely care if you did your flight training under Part 141 or under Part 61. What really matters is that you have the knowledge, skills, and experience required for the job.
Part 141 programs are more structured than Part 61. Because of this, it is possible to qualify for certification as a private pilot with a minimum of 35 hours total time, and for commercial pilot with 190 hours. The syllabus must be adhered to, however, and there are more stage checks, and often instructors are assigned to the learners.
