Are there any downsides to being a Battalion S2? Any reason it may negatively impact promotion boards in the future? Any negative sentiments?

S2 be, or not S2 be?

After 4 years away from aviation service, I'm very excited to be returning to a flight unit in the Spring. That said, I am also keenly focused on actively managing my military career, and have spent the past few months networking with units across the country to ensure my next role isn't perceived as anything but a professional step forward. This has proven to be challenging after completing an early first command. All mentors have recommended I vie for a primary staff role to avoid going from CO to PL or XO. I've already served and been rated as a BN S3 for 2 years and am inclined to try something new, but some of those same mentors have highlighted that not all staff roles are crated equal. There seems to be some balance one needs to strike between diversity of experience and remaining in the Top 3 (CO/XO/S3) camp as much as possible.

For those of you who have been S2s (or avoided being S2s for a good reason), would love to get your insight. There are idiosyncrasies to the aviation community that I'm specifically leaving out of this conversation to focus on basic officership and career management, but happy to hear from anyone who has specific experience in that world as well. Thanks in advance for the insight!
