If I understand correctly, all three are possible, but I don’t use it myself and only know these instructions in German. Here are the most important paragraphs (automatically) translated:
"Friendica allows you to make various settings. You therefore have the choice of whether and how you want to use the connection to Bluesky.
Even if the connection to Bluesky has been established and your contacts have been imported, this does not mean that all your Fediverse posts are automatically visible on Bluesky.
Friendica gives you the freedom to decide how deeply you want to integrate with Bluesky.
[ 1 ] ‘Publish to Bluesky by default’ - if this option is activated, every post will also be visible on Bluesky
[ 2 ] ‘Import the remote timeline’ - if this option is activated, all posts from the accounts you follow will be imported.
[ 3 ] ‘Complete the threads’ - if this option is activated, all comments on your posts and those of your contacts will be completed with additional comments.
Your connection to Bluesky is now established. Your timeline will now be filled with posts from the Fediverse and Bluesky.
You can now interact with your Bluesky contacts. For example, by entering a comment without opening the Bluesky app or browser window."
