Shameless plug for my own offering in this area - Kojo (15 years old and still going strong!): https://www.kogics.net/kojo

It's based on Scala, supports turtle (imperative) graphics, picture (functional) graphics, gaming at different levels (imperative, functional, OO), and more...

> However, there aren't any non-overwhelming "real" coding platforms out there.

For the past few years, we have been working on a Scala based 'real' coding environment that's easy to get going with (via Turtle graphics), but also supports more advanced stuff (generative art, games, circuits/robots):
