Last I knew fdroid didn’t support shizuku. Unless, you talk about 3rd party fdroid clients like droidify and neostore, etc. Also, unless xiaomi borked the adb perms(I’m sure they did like they do for accessibility service apps) shizuku can work with wireless adb.
I will link my comment, which I had written for another person before. Sync for lemmy is currently in beta, so some things may be broken. But, most of it is still true. https://lemmy.ml/comment/834817
