I use both a Canon 5D Mark III and a Sony A7 II and would like to avoid buying two completely separate flash systems.
Can any Yongnuo flashes work on both cameras? If so, which models?
I’m especially interested in whether TTL can work on both systems with one shared setup, or whether the only practical option is manual flash. If TTL is possible, what flash/controller combination would be needed?

I have a new Yongnuo flash, and although it is specific for the hot-shoe of my Canon, appears to know the protocol for optical slave for both Canon and Nikon. Neither my Yongnuo nor my Metz (Canon version) shows anything concerning Sony in the manual.
You might also look at Sunpak. It appears that the same core flash is used with different foot-modules to give the brand-specific stuff. You might enquire whether different foot-modules can be bought separately and how difficult it is to switch.
I also recall Sunpak making a pro flash that had different modules explicitly separate, but I think they cost more than the common Speedlight (or two).
May I suggest getting 1 (just 1) of each, and using the respective units for TTL on the hotshoe or wireless, and using all your flashes regardless of brand for manual mode multi-flash lighting or dumb optical slave (good for backgrounds).

Yes, but with an important limitation: a single shared flash setup can work on both cameras only if you use manual-only flashes. Both cameras have ISO-compatible hot shoes, so manual flashes can fire on either body.
For Yongnuo, a common option is the YN-560 III/IV with the YN-560-TX controller. That gives radio triggering plus remote manual power and zoom control, but not TTL.
TTL is generally brand-specific. A Canon TTL Yongnuo flash will provide TTL on the Canon 5D Mark III, but on the Sony A7 II it would behave only as a manual flash. Likewise, a Sony-dedicated TTL flash would only give TTL on the Sony, not on the Canon.
So if your goal is one system for both cameras, the practical answer is manual flash. If you want TTL on both cameras, you’ll typically need separate brand-dedicated TTL flashes/controllers for each system.
