No, no, no. Private browsing isn’t private like that. Your ISP and network adminstrator (in this case your employer) can still see every website you access. This is usually explained on the “New private tab” on browsers.
The use of Tor does show up on the network. The protocol is known and understood, and has been in the detection sets of pretty much every layer 7 filtering product for the last ten or eleven years. What, exactly, is being accessed is largely concealed (but traffic patterns give away a reasonably broad picture of what’s happening).
Portable Firefox is hit or miss, depending upon the work environment. It’ll definitely show up in file system monitoring, might show up in the logs of the border proxy as an unexpected user agent. The initial download will definitely show up. Removable media might or might not, depending on how group policy is set up.
What about private browsing or running a Firefox portable exe?

They can see what IPs you connect to, doesn’t matter what browser you use or if the connection is made from a browser at all
I mean it’s not blocked, but if you’re connected to their network, they can still see your traffic if they wanted to.
Yes of course. But OP is asking about Browsing history, which is basically the only think private browsing can do
“Tor browser bundle” is the version of Firefox that doesn’t reveal browsing data to the local network.

Private browsing is a fig leaf at best.
