I guess ‘cool’ depends on personal interest and circumstances.
A house move likely prevents running our Aussie Halloween this year, after being featured on State TV news last year, but I would like to share past family/friends efforts to establish a fun spooky celebration, in circumstances where locally there is not an established tradition, originating because my daughter in-law grew up in North Carolina and she and my eldest son moved here at the height of the pandemic, so I have adopted Halloween as a way to incorporate her fond childhood memories into our local family and local Aussie community traditions, with the help of family members and many talented friends: https://scarymandercove.au/
There are lots of choices, but personally I would go with Linux Mint as something likely familiar and packaged with pretty much all the basics for the use case you outlined.
