Go sub EDO option and transfer after your DH tour (~11 years of commissioned service) vice a SWO EDO option who transfers in after a JO tour (approximately 2-3 years of commissioned service).
Most restricted line jobs (EDO, public affairs, human resources, etc.) are comprised of former unrestricted line officers (warfare designators), mostly SWOs, who take an 'off ramp' somewhere along their career to lateral transfer into that designation. Each year a message comes out that details the year groups and quotas they're looking for, but the rub is that your parent community has to be willing to release you. For SWOs this is
usually not that big of a deal, but it can be very challenging for a 'due course'* sub officer to get released by the community in the vast majority of cases. Plus there is the fact that the Navy spent a lot of time and money to train you in the operation of naval nuclear propulsion plants, and they want their ROI, which means keeping you in the community until you either leave the Navy or prove that you are not competent enough to move to the next career milestone.
Now if you talk to enough people, you'll *hear* or maybe even meet someone who was able to lateral transfer from subs into a line community after a JO tour, but this opportunity is very rare and usually there are mitigating circumstances.
The bright side is that there are "EDO Option" accessions, meaning you have a guaranteed opportunity to lateral transfer into EDO after you earn a warfare pin before you commission.

really knows what your job in any of these spots would be:
