I would tell you to install none also.
Though they are nice services, they WILL add overhead to your applicance and the gateway scanning services drop your actual internet bandwidth.

Answers
Best practice = none <- that's not always the best solution for companies though
as for the original question, it's best to determine what is needed and what can done without.
CFS, does your company have strict internet use in place, if so keep this
Gateway AV, if you have a good AV program running on your network, you should be ok to disable this
Intrusion Prevention, is a good program to have running
Anti-spam, there are other solutions that don't reside on your firewall for this, spamhause is one that integrates with your exchange
>Best practice = none <- that's not always the best solution for companies though
Has nothing to do with being a company, individual, or other organization.
These are all add-on components. You can't just turn them on or off.
My assumption was, the licenses are not installed. They are by no means cheap...so it's hard to accidentally buy _and_ install them without knowing what they are.
>I'm running 3 firewalls at my office so I know what they are
I didn't see any useful information about zone application. Just generic recommendations about the technology.
For which zones do you have the products applied?
IPS can be applied on both WAN, LAN, and DMZ zones, so all 4 ports would be covered.
I still think content filtering is best left to LAN only. Same for anti-virus. Enforcement on DMZ servers could cause loss of connectivity or delay from multiple scans of the same content.

All of those services are add-on. So, for my installation, best practice = none.
We did run Gateway Anti-virus (McAfee modified product) which enforced McAfee installation on the workstations. It was OK. Nothing stellar.
We also ran Content Filtering. But, after too many complaints of bad keywords ...which were never removed...we had to disable it. "Tanzanite" was flagged and the user would get a warning page with my name and phone extension. I believe it is categorized as demonic or devil worship or something similar.
Those services are for the LAN. Possibly the DMZ for AV. I don't see how content filtering would work in the DMZ, as this is generally for human-operated computers, not servers.
