Have you read Lubuntu 18.04 LTS End of Life (30-April-2021)
and in particular the 4th post of that thread, where I did discuss alternatives.
My opinion today hasn’t changed; my release will have been updated from what it was in May 2021 when I talked about my eepc using a n270 atom CPU, but my OS is still the same, just as it is on my various pentium M devices (mostly old IBM Thinkpads, but also an old Dell). The graphics hardware dictates now, just as it did then, which release I actually use.
