Go PEX-A such as Uponor ... if given a choice. It is also make a difference on portable water source and what is in your water. Like Copper could and will react with well water.

This particular home is new construction with Flowguard CPVC installed.

I don't know much about CPVC, but a quick Google search found several reports of lawsuits related to CPVC. Most folks now use PEX, although a few diehards are still using copper (quite a bit more expensive). I would be very hesistant to buy a new house with CPVC, since better choices are available.

I switched to PEX a few years ago and have found it to be much faster and simpler to install than copper. There are a few places I still use short sections of copper (water heater feeds, etc.), but not many.

I’m in the commercial plumbing industry and thought this stuff was obsolete for under pressure plumbing systems - with the exception of multi family and some condo developments.

I was shocked to see it installed in 2020 built $800K homes. Thought I was missing something so figured I get some thoughts from the residential folks.

Personally, I prefer copper. Never had a problem with it in 45 years of home ownership, and never had to worry about rats gnawing on it. You might also want to do a Google search on Western conifer seed bug damage to PEX
