A limit nobody reaches
Facebook's post ceiling of 63,206 characters is high enough to be irrelevant. What constrains you is attention: posts are collapsed at around 480 characters on desktop and fewer on mobile.
Shorter posts have consistently outperformed longer ones in Facebook feed engagement, which is a function of how the feed is consumed rather than any preference in the ranking system.
The limits you will actually hit
Facebook caps other fields much lower than posts.

Limits for every other platform are collected under social media character counters.
