Well, "print as" is also a complex topic :) In Raku, the .gist method (which is used by say etc) prints both 1.0 and 1 as 1, but the .raku method (which prints the debug representation) prints 1.0 and 1. This feels correct to me – again, maybe because of time spent with Rust, which makes exactly the same choice.
Again with Rust, not only does 1 == 1.0 not return true, it doesn't even compile (without an explicit cast). So, from a certain point of view, Raku's behavior represents something of a compromise between the dynamic behavior of a language like Ruby and the type-system-enforced guarantees of a more static language.
And, really, Raku falls somewhere between those two extremes quite frequently. You noted Raku's clear Perl legacy, and that's definitely a big part of the linage. But Raku's DNA also owes a surprisingly large amount to Haskell due to a large number of Haskellers involved in the early design process (or so I've heard/read – I wasn't involved that early).

Haskell makes the same choices as Ruby and Python (and pretty much every other language):
