1. I'm frankly shocked that in 2025 you don't think endpoint protection is necessary on personal computers. I hope you never get hit with ransomeware...
Many businesses do require all their computers to be configured for Endpoint Protection, but they are using enterprise grade options. These enterprise grade options have caused us fewer issues than the traditional consumer & low level "enterprise" options provided by those older consumer grade vendors.
Sophos is a consumer based product that is not in the same tier (even if they do offer low level enterprise options). At one point my organization use Sophos, but only for a very short while before we moved away from it & several other traditional anti-virus brands. Today I would not touch any of the old traditional anti-virus products even if they are free. Most of those companies these days are providing inferior bug ridden products with gaping security holes while also selling people's personal information. The built-in protection provided by macOS and even Windows is perfectly fine for the majority of people as long as the users practice safe computing habits as outlined in this excellent article:
Effective defenses against malware and other threats - Apple Community
Only if a person is a high value target are other enhance security measures warranted, but I still would not use the average consumer based products currently available for the reasons I mentioned.
I stopped using third party anti-virus options back in the late Windows XP days once Microsoft's built-in option was performing on par with most of the consumer products. I've never thought to use any anti-virus on macOS except for my work Mac (using an enterprise grade EndPoint Protection) where it is required by my employer due to our cyber insurance.
3. I don't think either of these things is causing the problem because its been like that for a while. I'm much more inclined to believe that recently installing NoMachine is causing the problem, but I was hoping to find someting in the logs to validate that (besides just uninstalling it to see if the problem goes away, which I will probably try at this point)
NoMachine is a possibility as well, but I would suspect Sophos first & foremost because it is actively scanning the system & intercepting system processes whereas NoMachine is not. Plus at the time you ran the EtreCheck report you had performance issues, but NoMachine's extensions were not running.
I've seen people defend their use of anti-virus software, cleaning/optimizer apps, and third party security software over & over here on this forum using the same logic. However, those people who have uninstalled these types of apps have discovered all their issues magically disappeared afterwards. This is why all of the regular forum contributors advocate for never using these types of apps unless of course they are required by a school or employer. Even then, it is best to choose the least invasive & problematic option if allowed.
Is it guaranteed to fix the problem? No, but it is a necessary first step in troubleshooting since the user can always reinstall it later on if they wish. When troubleshooting issues it is best to go with the item with the highest probability of causing problems.
Of course everyone is free to do whatever they wish with their own devices. I can only offer my educated insights from years of personal experience supporting my organization's Macs and those of many family & friends & referrals, plus my years of assisting here & reading thousands of threads on this forum.
I would suggest perusing some of the other Sophos related threads here on this forum as you may find it enlightening:

I will try clearing some space on the main drive. 14.89GB is definitely not enough free space.
You should also delete the no longer needed files mentioned in the Clean Up section at the end of the EtreCheck report. There is a chance they could be causing some issues as well. Sorry about forgetting to mention that part.
Clean up:
~/Library/LaunchAgents/com.movavi.converteragent.startup.plist
~/Library/LaunchAgents/org.virtualbox.vboxwebsrv.plist
Good luck with your system.
