Lmao tbh right now i think of them as friends cause it just seems explicitly early, if they keep doing teases and hints in both the anime and manga constantly (which it probably already has) then it's gonna be the endgame. The time-skip would be interesting to see the dynamics between the two as Boruto will probably leave the village, for protection purposes, as Sarada will begin to worry and maybe bring him back? Anyways yeah in conclusion if the series just make Sarada a simple MC love interest then the ship will just completely lose itself, but if it continues its healthy treatment throughout the whole series, in which is has and hope it keep it that way, then yeah, they'll be the best developed couple of the NV IMO
