This is many markets, not one coast
Caldas da Rainha offers services and a hospital. Óbidos offers heritage and tourism. Foz do Arelho and Peniche offer very different relationships with the water. Rural parishes offer land and quiet.
A beautiful house in the wrong town is the most common mistake I see buyers make on this coast.
Value is real, but so is distance
The savings against Cascais or Lisbon are significant and can buy space, land and a garden. What you spend instead is time in the car and a shorter list of on-demand services.
Be honest about how often you truly need Lisbon, an international school or an airport run. That answer usually decides whether this coast is right for you.
