You're overvaluing high end work imo. You should probably at least for the next few weeks only have 2 days over zone 2; if those end up being group rides so be it and if you need more intensity that day tack it on but don't do it the next day because you have to rest or ride easy. Realistically you can really only ramp up the intensity 2-3 days a week, but mostly just twice a week. If you are doing 3, you're probably doing too much. 70% of your riding should be under 70% of FTP imo if you are doing volume over 10 hours. People undervalue easy rides but they help if you have the time.
