The ONLY way to "future proof" your cabling over long distances is to install your cable in a conduit. Video technology is still far outpacing connection technology so the likelihood of changing cables is very real down the road. Lifetime warranties are pretty much useless if you plan on exchanging the "defective" cable for the same one, if the mfr still offers it. There is more to a successful cable run than just the cable. Bend radius, wire gauge, the use of extenders/adapters, etc can all affect the signal path.
1080p is not a problem with cable runs over 25' (which is the current maximum certifiable distance). Active cables (Redmere) have a chipset in the sink end that draws a little power from the HDMI input for error correction, timing, etc which allows for longer runs without any signal degradation. Spectra 7 chipsets are the new chipsets so they should be able to keep up better with the newer video standards but even so, they are electronic devices so they can fail overtime or develop issues. They do nothing for pq because the cable is just a data pipe, and the active portions is just to extend the cable length, to a point. You either get the signal intact or not. For 1080p, a Premium High Speed HDMI cable, passive or active, should work just fine. The "Premium" means that the cable has been certified by an ATC as meeting all HDMI 2.0b hardware specifications. The cable will come with a QR label for authenticity.
4k HDR and beyond is much more difficult because the demands of the higher video technologies really push the limits of copper-based cables. A lot of folks start having issues at around the 20' mark. This is not absolute because some have good results beyond that, but not by much. The use of extenders, adapters, etc can help but anytime you introduce a "break" between source and sink, you can introduce issues. The best connection is a single run, source to sink.
HDMI 2.1, once commercially available, currently has a maximum cable length of 1 to 3 meters (3' to 9') for full compliance at 48Gbps. That basically sucks but such is HDMI. Hopefully the distance limitation will get worked out once HDMI 2.1 chipsets are installed in the newer devices. But all of your devices will need to have the newest chipsets as well for fully compliant HDMI 2.1.
If you don't have any plans on upgrading to 4k HDR anytime soon, then a well made passive High Speed HDMI cable from Monoprice, Blue Jeans, MediaBridge should work just fine. If you are thinking on upgrading soon, then you might want to consider a hybrid fiber cable from someone like Ruipro. They are expensive but should give you more mileage than a copper-based only cable. But this all comes back to the mantra of CONDUIT CONDUIT CONDUIT. However, if your cable run is easily accessible (on the floor, behind furniture, what ever) then you're fine without a conduit. In-wall installations should be done with a conduit without reservations. No wall plates either.
Cable mfrs will make all kinds of carefully worded claims that make their cables sound like they are the best made and will "guarantee" that you won't have any issues. That is just plain marketing b.s.
