You could also get 0patch to keep it secure. They're adopting Windows 10 for security updated from the EOL date. Pretty reasonable price as well, around 30 euros per year.
I was having a twitter argument the other day with someone who maintained that they never really come across any Microsoft systems in their work and who would be crazy enough to use Windows Server. I've worked in orgs from 100 people to 10,000 and it's always Active Directory and MS all the way through with odd few Ubuntu or RHEL servers for a internal application.
My main issue is still app notifications in the panel. IF I'm running a syning app like Insync. I want to have the app notifier in the system tray so I can see the status without having to check the service manually to see if its running.
Not a programmer, but I wrote my first proper script (lots of if/else) at 37 and the world of automation and scripting/programming opened up to me. I work in mostly a Microsoft land, Office 365 and Azure so I work mostly in PowerShell 5 and 7. My daily driver for work is Pop_OS! 20.04 as PowerShell 7 is decently multiplatform now. Current interests/learning are Python and Nim. I don't think you are ever to old to get started.
