Visually galaxies are quite varied, which implies, to me, they have a lot of variability in visible matter. Why wouldn't their supposed dark matter vary too?

They do! In particular, there are three of them out there that match expectations and thus have little/no dark matter! NGC 1052-DF2 (2018) NGC 1052-DF4 (2019) and AGC 114905 (2022)! Apparently there's another being discussed in a 2026 paper!
