Good question! I hadn't tried, but just found a random user on an instance that mine doesn't federate with and clicked Follow. It took me through the remote follow and that user did appear on my list and showed up in searches when they didn't before. Unfortunately I seem to have chosen an abandoned or dormant account for my test, so I can't say for certain whether posts will show up in Home, but I would expect so given the other visibility changes. Hopefully someone else with some fedi experience can chime in.
