My tips: make yourself marketable. Unless you go full on academic with publications, research interests, etc, try to find and love procedures, breast, and chest. MSK/Neuro are great too, but tend to be a bit saturated or readily supplied. Breast/body is a great combo skillset, but I don't know if there is still as much of a need.
The ability to do anything and everything is ALWAYS an asset, but comes with the trade-off of having to either be amazing at everything or risk spreading yourself thin.
Junior residents have plenty of time to overcome "I hate MSK" or "I hate breast" or whatever else happens early on. I wish I had driven myself to love MSK more, but I never found it my cup of tea.
My humble thoughts - would love to hear others'. Open to discussing.
