I feel like the stereotypes about SEI make it less likely for people to type themselves as SEI. It's like you should enjoy cooking things, hiking in nature, massaging people, feeding people, being the goddess of the hearth or something. And of course you are deeply aware of your physical states even though lots of SEIs are 9s and lots of 9s are so dissociated they can't feel their bodies.
I was about to say I think creative professions may be best for SEI. But there are plenty of SEIs who seem to enjoy their work in non-creative professions, like as admin assistant.
I think one needs a high IQ for programming and a working memory for details. SEI as a human type will have those among it with high IQs and good memories for details.
