she’s never seen using them yet her canon nature types are earth and water (the two elements needed for wood style)
yamato, the only other living wood style user, was literally her captain and could’ve trained her like naruto – and as a wood style user she could’ve trained with naruto by controlling kurama instead of sitting around with sai and watching
she’s the student and successor of tsunade (hashirama’s granddaughter) and surpassed even tsunade’s byakugou – as in, the closest jutsu to hashirama’s regeneration
from the beginning her character and narrative have heavily involved nature and growth (even down to her name – literally “spring field of cherry blossoms” – and color design – green + floral pinks)
she has a much higher focus / concentration and learning speed than naruto, who reached sage mode! she should be able to just as well!
sage mode is already taught by both the toads and snakes, so narratively the slugs should be able to teach it too – and sakura already has an established summoning ability and connection with katsuyu
just a little thing, but sakura’s clasped hands shown repeatedly in openings and endings could’ve grown from a passive gesture to one of strength – the snake hand sign iconic to wood style
not to be cheesy but let sakura go from a bud to a flower to a fucking Tree
