After exploring the Bridgy Fed to work out the difference between the two., I am currently exploring
This method seems to involve a few other steps, including adding a feed to the header and Safe Redirect Manager plugin. It also seems to be a bit more technical. However, I am assuming that the Bridgy Fed and Mastodon options recently added to Syndication Links mean that it can be controlled per most, as opposed to every post with the Activity Pub post.
I have followed the steps, but still trying to get posts to follow through. Maybe I need to have my new instance added to Bridgy? Not sure.
