Best Linux Distro to fit on 30 gig eMMC?

So I've got myself in a bit of a dillema. I got this HP Stream laptop that's only got 30 gigs of storage, and I want to use it for work. I already bought a 64 gig SD card that I have for storing encrypted files, but even with that the storage on my eMMC runs full. I'm currently running Manjaro Linux Xfce minimal, I use brave as my browser, xfce and awesome as des, nextcloud and megasync, kate, minecraft, teeworlds, xonotic, libreoffice, and other mesc. stuff. An easy solution would be to just uninstall software, but I would like to use this software, I actually use a lot more I'm already going as minimal as I can.

Basically, what is the best setup for storage on a 30 gig storage device? I'm talking distro, file system, de, kernels,live compression, whatever. All I want is something I can program, access the internet, has good second-monitor support, and play some games on. Your thoughts?
