Since you mentioned little interaction and reactiveness, I would say go for htmx. At work, we have a large MPA in ASP.NET. If a page is simple enough, it is done in Htmx. If it requires lots of interactivity, we use Vue. But I tend to push the boundary on what counts as enough interactivity to warrant the use of Vue very far, and I prefer to do most stuff in htmx these days.
