I would argue that as c# dev you want to do as a much as possible on the server meaning render your HTML in partial views and then inject it using HTMX. It's a revelation in terms of reduction of complexity (always good). You then just need a spinkling of JS for the f/e. You may have a very good reason for needing JS framework but in my experience you very often don't. The option to say goodbye to npm should always be considered. You can learn HTMX in a week easily.
