Don't sweat the decision too much. You can't go far wrong either
way. It isn't that hard to switch later, in either direction.

Scala 2 remains a common and reasonable choice. Most Scala jobs are
still Scala 2 jobs. Scala 2 also has a somewhat bigger library
ecosystem, somewhat better tooling support, and somewhat wider
availability of learning materials.

That said, these gaps are getting narrower every month.
Plenty of books are available, a rich library ecosystem already
