May someone be so kind as to offer advice if a certification in accordance with NAS 410 is recommended or if the SNT-TC-1A, ANSI/ASNT CP-189 standards are sufficient for success in the the majority of the field? Please let me know if you have any questions and thank you in advance for your response.

It depends on which industrial sector you want to work in and where you live / want to work.
NAS410 is primarily an Aerospace qualification, and in Europe, we tend to use EN4179 as a parallel procedure (in fact the two specifications are so similar that certification is often extended from one to the other with one examination).
EN4179 is however a Company Specific qualification, but the General paper can be "transported" from one employer to the other, with only the Specificf and Practical papers to sit for the new employer.
Inside France, the Aerospace industry used their own scheme (CCA POP 94 001) which is based on EN4179
SNT-TC-1A is a Company Specific paper and as such is not transportable with the operator when he changes employment.
Please take care to differentiate between SNT-TC-1A (administered by ASNT) and an ASNT ANSI certification. many people with SNT certification falsely claim to have "ASNT" certification.
ASNT also offer certification ANSI/ASNT CP-189 (portable) at levels 2 and 3. here, the general paper is also recognised by other schemes.
Other schemes are EN473 (European general purpose certification, but with specific sectors defined) and ISO9712 (similar to EN473).
Perhaps a little confusing, but decide where you want to work and in which sector, and then start looking at the different schemes available.

One of the important issues with SNT-TC-1A that is often confused is that it is NOT a specification. It is a recommentation (a "how to" guide, if you will) that describes what SHOULD be in a specification or internal procedure. It does not mandate anything. Where as ISO 9712, NAS 410, EN4179 (and others) precribe the minimum that SHALL be in the internal procedure and the minimum qualifications of an inspector.
In theory, someone that shows up for work and has "ultrasonics" written on a piece of paper on their desk, COULD meet the requirements of an internal procedure that "meets" SNT-TC-1A. I am being a bit sarcastic, but the reality is that a "certification" to SNT-TC-1A may not be worth the piece of paper it is written on.
As Geofrey describes, only "portable" certifications, as such, meet a true minimum requirement.
