Considering the current intrusive cyber climate, what are the best ways to preserve privacy?

For example, I have been exclusively using a VPN connection network-wide at home setup on OpenWrt, which in turn has a PiHole as its DNS, with the PiHole using Unbound and NextDNS (redundant I know, but I use it to encrypt my requests more than anything else).

I also have Wireguard setup so I can VPN all my devices to my network while I am on the road (also have a NextDNS profile installed. Yes I know, it’s redundant).

I also basically have all my “smart” devices (TV, lightbulbs, air purifier, etc…) at home cutoff from the internet using OpenWrt’s firewall to prevent them from calling home.

I rotate web browsers frequently to try and attempt avoiding getting fingerprinted, not sure how useful that is.

I switched email providers to mailbox.org because f*** Google and Microsoft.

I also am hosting my own cloud drive on Nextcloud to avoid using services like GDrive, OneDrive, Dropbox, etc…

I own Apple devices which aren’t the best for privacy but migrating from a whole ecosystem that I have been embedded in for MANY years is easier said than done. Hopefully in the future that’s my next move.

I feel like there is a lot more I can do but I am not sure what else. I would appreciate any and all suggestions ya’ll might have.

EDIT: I’m not being too extreme with my caution as some comments are making it sound to be. I am a very average person who is privacy conscious yet realize being cut off from the internet and society is not realistic. I guess my threat model is your basic “day-to-day it’s non of your business who am I online or what I do, please don’t profile/fingerprint me, I am just a passerby” kinda threat model.
