Should I create a new user account to try Hyprland?

I would recommend it. I did it on a KDE user and what happens is you need to twiddle things to point browser to use kdewallet.

So I have a new user that is running hyprland. I got it to a point I like after trying

And one other that a user here created.

I ended up with JaKoolit as my default install but you should try them all.
