Clarification on maintenance items

I am new to this forum as a member but have gotten lots of great tidbits when needed over the years. My wifes car is a 2014 Prius V gen 3. its a great car and we love it. its over 100K miles and we are noticing some typical things that wear. I'm about to delve into shocks and struts but more importantly i'm getting into changing important fluids. I change the oil and filter every 5000 miles so that's not an issue but I want to do all the other fluids. is it my understanding that the only fluids that need changing like the oil is the transmission fluid and the inverter fluid? I figure I'd do both at the same time while I have the lower panel off. remedyiing the weak headlights is going to be my next big investigation, haha. thanks for your insight
