Short answer, for me personally: No preference, whichever is fine, in whatever frequency you like. For a longer answer, I wrote a thread a while ago that still mostly applies:
i did eventually land on she/her exclusively but when I was using multiple, yeah, I was trying to signal a preference with the order. i changed the order from they/she to she/they, as I got more confident asserting (to myself as much as anyone) that I wanted to be she/her'd.
yes, basically. also depends how im dressed/presenting.
I prefer they/them, with sher/her as a nice once in a while treat. So yes, order does matter to me here in bluesky. That said, it's not a fixed thing for me. I flip them around a lot with folks I'm close with.
I see it as I expected the 'she' but if I get the 'it' it's a pleasant treat. If I got it too frequently it'd kinda spoil it.
