If you just want to play around with it, I highly recommend some arch based distro (because you can find plenty of obscure TUI apps in the AUR) with a window manager (be it tiling like Qtile or stacking like Openbox).
If you want something preconfigured, I've recently found instantOS, which seems to work fine for that usecase.
I use this small laptop mostly for ebooks (using the excellent epy) and music, using one ot the TUI YouTube frontends.
Recently found out about ouch. Found it really useful for decompressing files in the terminal as I can't seem to remember all the flags for tar, gzip, zip, rar and all the rest one may encounter which all seem to use different syntax.
