I really don't have any custom needs. Any old linux distro will do.
But only 2 to 3 years? That is very short. What would be a good alternative with longer support? There must be market for it I guess. Don't companies simply want to run their stuff as long as possible? Many companies still use Windows XP. And that's 14 years old.
Any major distris that commit to 10 years of support or something?
Yes, RHEL has 10 year support periods. Red Hat Enterprise Linux is commercial - you pay an annual subscription for updates.
CentOS/Scientific Linux/Springdale Linux are free clones with free updates. Oracle Linux is a free download, but not sure how updates work. Current is version 7 with support until 2024.
PS: if you are asking this kind of question here, you might want to take your local Linux sysadmin for coffee and explain your use cases, applications, hardware spec and likely traffic in detail.
