Run the cable direct to the TV where I plan on upgrading to a LG OLED or a Samsung 8k and trust in eARC?
Thanks in advance!

There are no certified cables for the complete HDMI 2.1 options sets, especially at 75', regardless of what the cable mfr lists in their marketing and product literature.
The ONLY way to future proof is to run your cabling in a 1.5" - 2.0" conduit. Video technology will always outpace connection technology to so you need a safe and easy way to replace/upgrade your cabling when the time comes. Besides, there is no way of knowing how a cable purchased today, especially at 75', is going to work once devices are in consumers hands that have HDMI 2.1 chipsets that are certified for all of the HDMI 2.1 option sets. The cable is just the data pipe. It cannot alter or modify the data that is being sent from source to sink.
4k HDR is very finicky with its connections so the most reliable connection is source to sink, with no wall plates, adapters, extenders, etc in-between.
A 48Gbps cable right now is all marketing because there are very few consumer devices that can transmit at that bandwidth, nor is their source material available that requires that. HDMI 2.0 is standardized to 18Gbps so even if you had a cable that could handle 48Gbps it is meaningless.
Distance is going to be your biggest issue, especially for eARC. For those that can currently do eARC (which is possible on the HDMI 2.0 chipsets), 50' seems to be about the maximum reliable distance. Hybrid fiber cables, which are active, are your best bet (Ruipro4k and the coming 8k cable) but even then, you may need to use a voltage inserter if issues occur.
Whatever you do lay the cable out on the floor first and thoroughly test it before installing to make sure it meets your needs.
No cable can offer you a 100% guarantee that it will work with all setups and installation schemes so just remember that. 75' is gonna be tough.
