For those asking what my current plan is:
I'm going to push forward on migrating my use of more complex web apps to a standalone equivs where available (e.g. mastodon / rss readers)
In the short term, probably tor browser to do more general browsing. I trust that team to be able to strip out most of the bad, and keep the rest generally locked down.
Long term: It's time to really commit to building something better.
