What other 95k maintenance when I clean EGR?

On this last day of 2025, my 2012 Prius V is at 95k and still on factory original:

1. inverter coolant (tested full alkaline with test strip, color/smell is like new)
2. engine coolant (color/smell is like new)
3. front brake pads (still many mm left)
4. rear brake pads (only about 4mm left)
5. brake fluid (tested zero moisture with test strip, color/smell is like new)
6. spark plugs
7. eCVT fluid
8. EGR components never cleaned
9. PCV components never cleaned

I have replaced engine oil, oil filter, engine air filter and cabin air filter every 5000 miles, and I put STP injector cleaner to my fuel tank at oil changes.

I plan to do a full EGR clean in the next few weeks. So while I have things taken apart, should I just replace everything at once? I know the plugs can last longer, but they will be easier to reach while I have everything taken apart. My fluids test okay, but they are 13 years old so might as well replace them all? I'll do the eCVT fluid separately since I don't think that is connected to anything else.

And what other non-standard maintenance items should I do while I'm in there? For example, the manual doesn't say I should clean EGR but I'm going to do that anyway.

I also need to replace my old tires and leaky struts, but I will pay a shop to do that in the spring. I might pay them to replace the rear brake pads at the same time.
