What data?
It’s possible there’s something in the firmware or BIOS that transmits some things to Apple; I do not know for sure, but maybe someone else will show up here who knows details about this. Even if that is so, Apple gets significantly less data because anything built into macOS won’t be running.

I don’t think there are any viable engines other than the three you mention. Other browsers than the three you mention are viable, I am typing this in LibreWolf, but they are all based on one of these three engines.

I think you can publish on many ordinary (micro)blogging platforms through Tor, but you’ll need a valid email address.
So the problem is reduced to: how can you get a valid email address through Tor that is not linked to either a phone number, your real identity, your credit card, or another email address that has any of these pieces of information stored.
I have never needed to do this, but to my knowledge, there are email providers where that is possible. Another user linked to privacytools.io where I can find this list https://www.privacytools.io/privacy-email - so that may be a place to start.

Nearly all open source map apps (definitely OsmAnd and Organic Maps) use openstreetmap.org as a data source which is literally a wiki, ie. anyone can edit it. If there is a lot missing in your area on OSM, then please add those things yourself. It is exactly as good as volunteers made it.
I have no idea how government regulation of the Internet has become so normalized.
