Yeah, I mean, I share those concerns in general, but my efforts are mostly centered around aggressive ad/tracker-blocking (moderate DNS-level blocking at the network level, more aggressive at the device level + browser-level blocking) and the avoidance of non-privacy-focused services, e.g. avoiding the popular social networks entirely, and using privacy-supporting pay-for services.

Using the same IP for all of my devices, for me, generally falls into the same bucket of anti-fingerprinting techniques that are used by the Tor Browser like letterboxed resolution that I don't find practical for general use. If I want to actually prevent fingerprinting by IP, resolution, etc. then I'll actually use the Tor Browser.
