This is going to be unpopular, but you can easily compile both Python and R and configure them to your liking. For Python you can even use Anaconda3 and forget about installing most packages by yourself.
As for Julia, I usually just install the precompiled binary package.
So, any distribution you feel comfortable with will do.
I use Yarr (Yet Another RSS Reader). It can be easily deployed with Docker Compose and does the job nicely:
