With analog signal cables, one can argue the merits of high-end cables (I'm not saying that there are merits, simply that there is room for discussion), but with digital cables, bits get there or they don't - there are no premium 1's and 0's for high-end systems, so, your super-high-end TV won't display better with high-end cables, as long as all the bits are arriving. And if they're not, the picture damage will be dramatic, not, "oh yeah, I think it looks a little better/worse".
For typical behind-the-TV connections, any decent quality cable should work. I recommend MonoPrice (long the nerd's secret weapon - it helps one's confidence to see several hundred positive reviews before buying a $5 cable, and I don't think they're gaming their own review system), or AmazonBasics. It's not that the others won't work, just that going with a sure thing means statistically fewer headaches.
HDMI _does_ have a problem with long runs (it's actually a pretty
poorly designed standard); if you're doing something over, say, 25 feet,
and want to guarantee that it works the first time so you won't have to rip out and replace a bad cable, I'd recommend looking at
Blue Jeans Cable, because they've actually done the R&D and engineering work and their cables aren't just coming out of the same factory in China as everyone else's cables. Their improvements to the cable don't involve shiny marketing, holy water, or piles of MadeUpTerms™. They have a
collection of articles on HDMI that are pretty interesting, and which are the reason I've got MonoPrice cables behind the TV, but a 30ft BlueJeans cable for the one that snakes around the room to end under the couch (for occasionally plugging in laptops).
