In that case I would try to specialize, at least for marketing purposes.
For example pick Angular/React/Vue instead of typescript/javascript or another specialized stack.
If most of your colleagues are doing c# mvc then don't do the same thing, but complement them. Either pick a frontend technology as I already mentioned or do openapi specs or something else that's useful for your ideal client.
In my experience people prefer hiring specialists and will overlook other missing qualifications if you tick a core skill.
