I wrote CmdVees to scratch my own itch.
It works like a stack. You can copy several items in sequence (like any clipboard manager) but when you hit Cmd-v, the pasted item is removed from the stack. FIFO.
It may sounds weird, I guess it depends on how your brain works. For me is very natural. There is also queue mode for the other brain model.
Also, it splits entries in history by time, hiding older items in a submenu:

To be honest I don't use the menu more than once in a while.
It has other goodies like joining items or swap top of the stack with selection.
It's a commercial app but feel free to ask me for a license if you fall in love with the trial and you can't afford it.
