HDMI from TV for longish run to stereo system

I use my stereo system primarily to listen to music.  But in my music room I have a new smart TV that I occasionally watch.  I want to use my speakers rather than those that came with the TV (which goes it’s data by Wi-Fi)   I have to run an HDMI cable about 30 feet from the TV to my components to do so.  I’m told that I need to get active HDMI 2.1 cables for this.  I was shocked by how expensive some of these are.  I would appreciate recommendations for cables for this purpose.  What specs for the cables would be relevant?
