It hasn't been stated if it's the end or not. I think it'll depend on if it's paid and then if it's only Chapter 2. Toby Fox had to hire a small team due to issues with his wrist so it's all very unclear how far along it is. Honestly, I'd probably wait too if I didn't have friends who I know are going to be talking about it. Same thing happened with Final Fantasy 7 Remake. Gotta jump on that while I can avoid spoilers.
As for Beastars, well, it's no Odd Taxi, that's for sure. It really only gets batshit for the season 2 finale and that's because the actions of characters feel so extremely stupid and the visuals triple that feeling, like Dragon Ball Z levels of visual transformation which is... a choice lmao. The opening and closing tracks are indeed really fucking good, but if you weren't a fan of Season 1, I don't know if it's worth sitting through Season 2 and its melodrama. It's very much more of the same except they finally remember their classmate was murdered back in episode 1.
