I agree, actions (what and to which degree needs to be done) will differ if you plan for 1.5 °C or 3 °C.

The degree (no pun intended) changes, but the kind of actions you engage with are more or less the same.

This, from a business point of view, if we talk about things like "the entire city will flood in 20 years" (which is what would happen to some places on the 5ºC pathway), then there's not really much to do, honestly.
