I also tried a bunch but am now keeping Matomo. I like it for its cookieless (and as such consent-less) mode.
what I miss from GUA/GA4 is a "top pages" report. Matomo seems to only support a url-path-based treeview like Pages report which makes it quite difficult to find the top performing pages if the site has many sections/categories
while I share your sentiments regarding some other companies, I was able to get in touch with an actual cloudflare technician (and not some outsourced first level support with standard boilerplate replies) in a timely manner even on their free tier when I ran into a problem with one of their system. every support case with them has do far been a real pleasure compared to what you experience with other companies. I only hope they will be able to keep this level...
