Or does a self hosted lemmy instance federate all comments from all threads once it knows about a server?
Only in subscribed communities, but yes.

Wayland fixes a number of bugs and fundamental issues in X.Org. It is also much more actively developed, and it seems likely that over time new hardware will stop working with X.Org due to bugs nobody is interested in fixing (this is already the case for the Apple M1/M2 GPU drivers).
On the other hand, Wayland also introduces a number of additional bugs. However, some distros like Fedora have enabled it by default for years. In practice, most of the bugs relate to at least one of Nvidia's drivers, DPI scaling, and DEs with less mature support. If you're using an AMD GPU, 1080p display, and GNOME, you'll likely have few issues and possibly even a better experience compared to X.Org.
On the other hand, I don't really trust Reddit with my upvotes/downvotes all that much more than random users, so I already refrain from voting on content I wouldn't want to be associated with....
Of course, Reddit can still see what posts I view, while that isn't the case for Lemmy (at least since I self-host an instance).
I believe this is the number displayed if you view the community on the original instance?
