In case anyone else was curious, yes, you can download a dump of Wikipedia - https://en.m.wikipedia.org/wiki/Wikipedia:Database_download

Back when I got off in 2019, there was a tool (Facebook sponsored somewhere in the settings) that allowed you to save everything in an offline HTML file that you could host locally and get access to things like picture albums, complete with descriptions and comments. Not sure if it still exists, but it made the process incredibly painless getting off while still retaining things like pictures.
