The Tulip Creative Computer[1][2] hits a lot of your points (I'm just a customer). It is definitely not a retro computer with an 8 bit processor, limited memory etc. Instead, it uses modern technology (ESP32S3 microcontroller with megabytes of flash memory and RAM, color touch screen etc.) and runs a modern programming language (MicroPython) that also serves as the operating system.
This particular product might not be exactly what you want, but it shows that you can use these technologies to build a computer that is much simpler than a modern PC in both hardware and software, but is still very capable, and intriguing to use.
