But anything made in the last few or more years is 4K now and everything I watch is 4K, so all I find is HEVC stuff for everything.

Sure, if you are going to go get an older show that's pre 4K/HDR or a movie that isn't on UHD disc yet, then it will be H.264 of course.

But if you primarily watch newly made 4K/HDR content, it's all been HEVC for years now.

Again, depends on your source content. Obviously 4k/HDR is H265. Plenty of shows are still 1080p source though even today. Not the 'flagship' shiny ones, but there's a lot more 1080p max source content. And for those, the proper format is H264, and still is what is released today.
