Pretty much, yes. I've never encountered a game that I couldn't describe more clearly with different terminology. I also don't like "Action RPG" because to me it's an oxymoron. Action games are at one end of the spectrum, while RPGs are at the opposite end. A game can't be both at the same time. A so-called "Action RPG" is neither an action game nor an RPG. If one is aiming to describe a game in the middle of the spectrum, that's what "Adventure" is for. Anyway, I'd have to play those games first to describe them. But I imagine I'd call Ys III a side-scrolling adventure game, just as I would with Zelda II, Faxanadu, Battle of Olympus, etc. etc.
