Can’t speak to whether you need both USB and digital coax in your system. I use both but that hardly constitutes a universal requirement.
As far as "great performing/great value"...
For USB, I thought the Oyaide neo d+ Class A was IT (see the Absolute Sound review) until I happened on a write-up in Audio Asylum by Duster about a USB cable from Monoprice...one of their Monolith products. Ridiculously low price. I tried it. Very, very, very good sonics. Better in my system/to my ear than the Oyaide. Go figure.
As far as digital coax. I like Chris Sommovigo’s stuff. Have a Stereovox XV2 and a Silverstar! 75 Mk I. I think pricing on his more recent offerings leaves a good bit of room for debate about what exactly "great value" means. Maybe find one of his earlier designs used? Your mileage may vary, of course.
I have not had occasion to use an ethernet cable.
Hope this helps.
