With that in mind, is this actually in need or replacement? Have a cylinder 1 misfire, and I’m praying it’s just the spark plug.
Replacing anyway, and I’m getting the igniter coil tested. These are the spark plugs that came with the vehicle when I got it, so worst case scenario is they have 115k miles on them

Spark plugs are never the problem unless you buy no-name Aliexpress specials. This is 2023, not 1953. Don’t throw parts at the problem.
Swap Coil #1 with another, wipe fault codes, run the engine. Did the fault code migrate with the coil? If so buy a new coil, install and you are done. If the fault stays on #1 first read fuel trims, both short term and long term. How are they?
If you see something weird with fuel trims (especially short term flickering too much), send the fuel injectors to be bench-tested as a set.
