Thank you for the sceenshot.

Q1. "Content & privacy stays toggled on 'Don’t allow changes' even after clicking ‘Allow’ for Photos and Calendar"

A1. Turn Off the VPN --Rather, Delete it:

Unless required for school or work, delete the VPN. If you need it, then disowned from it. Security Software can get in the way on an iPhone, and this is a pure example of how and why.

Two Safaris:

Q2. "Also I have two safaris listed and I’m not sure why. I should not have a corporate/organisation/enterprise/School Management iPhone. I’ve called Apple several times now and but issue is still not fixed. Also it did not fix with the latest update. 18.4.1."

A2. Not certain where there would be two Safaris. One does not have an icon, indicating it may be part of your cache. So, clear your System Data, as seen in my User Tip: How to Clear "System Data" in your iPhone's Storage: - User Tip
