I would choose the Adeptus Mechanicus
BUT I'm a girl, I would guess that would mean Adeptus Sororitas for me
anyway there both pretty intresting.
(are there tech-priestesses)
Yes. Sadly, they trend towards being mono-gender and thus it's very difficult to tell a female tech priest from a male one until they speak. However, there are other roles inside the Adeptus Mechanicus in which female are a little more, well, female, but those tend to be jobs subserviant to higher ranking priests or aids to princeps.
As for my choice? If I could pick
anything I'd go with the Ordos Hereticus, with training from both the Culexus and Vindicare temples. Searching the Imperium from within with the powers of the null-psyker and elite sniper training would be one of the safest and cushiest jobs ever, without being terribly dull. Gotta kill the heretics to get the paycheck for the wife, y'know!
Barring a relatively normal life, I'd probably want to be an Astartes. They're just so awesome. Not sure which chapter, I think they're all pretty cool.
