You do need to sign in to Firefox sync on each version if you install both as 2 unique applications on Android don't share each other's data.
On desktop front there is no problem connecting current and nightly to the same sync account and indeed same profile directly.
The sole annoying thing about nightly is that it naturally updates frequently. It's quite stable and gets legitimately useful features faster and let's you disable signing and run locally built add-ons. I use it as my primary browser on Android and Linux.
