Streaming: WiFi or wired??

Also, with higher frequencies (at 5G) , your signal degrades quicker so distance becomes more of an issue. This is laws of physics and you just have to live with it.

This and the fact that higher frequencies penetrate walls poorly prevent interference from outside.  In addition on 2.4GHz band each channel is 3.5 channel wide, so in reality there are only 3 to 4 completely independent channels.  My microwave was on one of them causing dropouts, neighbor on another etc.  I've never had dropout, since I switched to 5GHz (less traffic, more channels etc).  With WiFi I don't have to worry about anything on computer side.  Receiver (Airport Express) has small jitter on digital output, but it is suppressed by the DAC (Benchmark DAC3).

Wired is twice as fast as wireless. That should be the deciding factor.

No, it isn’t. What you need for typical CD is 1.4Mbit/s while WiFi delivers 54Mbit/s. Streaming services most of the time use lossy compression so it will never sound as good as original CD. AFAIK Tidal HiFi supports lossless streaming at 1.4Mbit/s rate (same as CD), but it costs more.
