I just purchased the PS5 DC for like $20 or something stupid cheap (i'm guessing bc i owned the PS4 version, as the regular PS5 version was full price on PSN but the top one wasn't??), and transferred my save last night. Have not had a chance to play it tbh so can't really comment personally however have read that it definitely reduces the grind. I don't recall the grind being an issue though tbh, except perhaps for roads. That being said, playing it in 60fps, smoother overall gameplay, and some cool little additions makes me excited to jump back in and i doubt you'd be remotely disappointed if you played DC as your first go.
