Do audiophiles switches improve the sound? Yes but to be noticeable one must have a transparent enough system and get a high enough audiophile quality switch as many lower efforts are commonly sonically lacking.
Because you have the high quality N10 streamer, suggest getting at least the EtherRegen which is not much money. SR is a good choice for more money, but the best performance seems to be Network Acoustics or Reiki.
Ethernet switch worthwhile?
That’s a personal subjective call. I’ll eventually purchase the Reiki switch+LPS and it’s Reiki’s JundoStream Network Cable after the positive Stereophile review as I’m into dropping the noise floor in my highly revealing system - I’m still trying to rationalize my spending justification to myself 🙄
