You don't seem to understand that one can do behavioral tracking without sharing all personal data with Facebook and Google. GDPR is mainly focused on who you share the data with. Performance tracking of core business processess including traffic sources can be done without involvement of Facebook and Google.
It's totally legit to spend a career helping the folks at Facebook and Google to soak up more private information about everyone so the Trump campaign can improve targeting of the fake news advertisements for the presidential election campaigns. But it is not ethical.
Disagreed. You can absolutely do all analytics, personalization and marketing in-house on your properties. You only need data sharing if you want to influence advertising on other properties or if you display others' ads on yours.
Whether you want to do so is a different matter. This obviously requires (potentially custom) software and infrastructure, vs throwing in GTM and calling it a day. If there is no regulatory reason for it (there isn't - this aspect of the GDPR is not enforced), most businesses won't bother and will take the easy option.
1st party behavior tracking still requires consent. And nearly every business needs third party integrations. I’m still waiting for someone to give me a working example (a real business )
The level of "tech" for a lot of trade and local businesses is often just a mobile phone and word of mouth, no online advertising industrial complex necessary. Those are still very real businesses. When advertising is used it's likely "old school" advertising with no tracking or analytics.
Ironically, if you are looking for a tradesman and do stumble upon an online ad or very polished web presence, be wary as it's basically guaranteed to lead to a boiler room full of scammers who will overcharge you and farm out the actual work to the lowest bidder.

You are confidently incorrect. Consent is not needed if you only track for your own business and do not send the data to other businesses. One of the big GDPR-compliant website analytics tools, matomo, even has a dedicated page on this topic: https://matomo.org/blog/2021/10/matomo-exempt-from-tracking-...
"Matomo has also been approved by the French Data Protection Authority (CNIL) as one of the select few web analytics tools that can be used to collect data without tracking consent."
