This is the second time that I have owned a device where system is too small for /e/OS.
For ocean listed above e-3.2 was built as eng MINIMAL_APPS and there was some headroom
~$ adb shell
ocean:/ $ df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/block/mmcblk0p63 2.6G 2.4G 145M 95% /
but I guess e-3.3 is a bit larger. A generous spirited offer but any amount of testing cannot create space for a build with Advanced features installed to system.
Would ofc be LineageOS. Lineage4microG (after their downtime clears) may be available for some affected devices.
