Wifi vs hardwired for streaming

My mid-50's ranch is swathed in aluminum siding and has two wire circuitry in most parts of the house. I have recently switched to fiber internet with newer mesh units and the video has improved, primarily in terms of buffering and general connectivity. Also, dropping AT&T copper internet has all but eliminated wifi dropouts and general bandwidth issues.

That being said, my streamer is is about ten feet away from my router and is plugged into a different circuit. I'm using an ethernet connection using a slightly upgraded cable. Unless I move my system to another end of the house, I will stick with wired a connection. I can't easily make a long ethernet run due to having a slab construction and an attic full of cellulose. 

I prefer Ethernet.  The only downside is having to hide the cables.  I have a home configuration that makes this very easy but of course that is an individual issue

Is there any advantage to putting a Wifi mesh point next to my equipment and using ethernet into it over using the streamer's built-in WiFi? I'm getting good signal into everything using the built-in WiFi.

That’s how I am set up except I hardwire from mesh node near streamer. Sounds and functions great. I have tested this against the same using WiFi connection. No SQ difference. I rarely had dropouts with WiFi connection. Never have .them in this set up.

I compared a 30’ Blue Jeans cable to a TPLink Wi-Fi extender with a shorter Ethernet cable running to my Innuos Zenith Mk3. The Wi-Fi extender with the shorter run gave me a notable improvement in terms of clarity and blacker background. I have since added a Stack Smoothlan, and now upgraded to their Regenerator, both offering further improvement. Regardless of which transport method you choose, I would recommend some kind of filter device near your streamer.
