Is it necessary to have the same coating on parts? Ie ONLY phosphate with phosphate? Or is mix and match okay knowing one part may wear out faster than another

Plenty of parts are different, anodized frame with a stainless steel slide/carbon steel/melonited/coated slide.
Ar‘s can have multiple coatings like chrome lining with parkerized barrel, inserted in an anodized upper held in place with Parkerized pins, and a Tin coated bolt.

honestly I don’t believe mixing coatings on gun parts would be an issue.
It's typically not an issue, but just remember that -ALL- parts can potentially carry tolerance-stacking issues, and that non-standard coatings, regardless of what the company's reputation may be or what they claim the coating may do, *_can_* potentially exacerbate such concerns.
If you watch enough of the SOTAR gauging videos, this becomes very apparent. Albrecht is very careful to note that what he has in his hands is an n of 1, a unique sample. But remember, what you will have in your hands will be that "same" n of 1, too.

Coatings can definitely create diffences in tolerance especially when using cerakoted parts.It's typically not an issue, but just remember that -ALL- parts can potentially carry tolerance-stacking issues, and that non-standard coatings, regardless of what the company's reputation may be or what they claim the coating may do, *_can_* potentially exacerbate such concerns.

Honestly hadn't considered tolerances.
My biggest concern is I'm using a nitride BCG (bought one on sale @ PSA for around $75) and was wondering if a phosphate barrel would be an issue?

Shouldn’t be an issue whatsoever.

Those 2 surfaces aren't mating with each or have reciprocation parts of same surface. Even so I use np3, ceracote, phosphate, chrome and nitride surfaces together in a BCG, receiver and buffet tube of any combined coatings. BCGs also have used a combination of surfaces that move within each other.

That would be evident with any moving parts, but some will wear less giving the same amount of use. Some coatings are better against corosion, carbon, dirt, water or temperature. This is where proper lubrication and maintenance come too play.

Anderson Manufacturing has a RF85 coating that they claim to run 85% less friction and no lube with only soap and water too clean. I have a few barrels from them , but no RF85 rifles.

Nitriding is a surface treatment that enters the metal itself, and adds no additional coating to the metal surface.
You can use any BCG that was made to the proper AR-15 spec no matter the coating.
PSA actually makes a decent BCG so I'd be surprised if it was out of spec.

Phosphate (aka Parkerizing - zinc or manganese) is on the exterior of the barrel, not the locking lugs/chamber/bore parts of the barrel.
