As a professional network engineer , I agree completly .
100 mb at home is fine unless youve got a local SAN and you doing video editing.
Cat5e will be fine for home, but cat 6 and above is better for speed.
BUT, it has to be done to specs. Bend radius, no DIY terminations, Velcro not cable ties and a few other bits and peaces.
WiFi 6 will probably make a lot of cabling obsolete.
