EOS 6D Mark II Question about compatibility with Speedlites

[Lmunk47]

I’m looking to purchase a speed lite but I’m not sure which is compatible with my Canon 6d mark II.  Does anyone know which one works for my camera?

Any one that has the traditional pins and NOT the new multi function shoe like the EL-10 and EL-5.

All Canon EX speedlites and the EL-1 and EL-100 are compatible with your camera. Newer models such as the 90EX, 270EX, 270EX II, 320EX, 430EX II, 430EX III-RT, 470EX-AI, 580EX II, 600EX-RT, 600EX II-RT, EL-1, EL-100, MR-14EX II & MT-26EX-RT speedlites and ring lites will have full compatibility with the in camera flash menu. Older speedlites such as the 220EX, 380EX & 420EX have partial compatibility with the in camera flash menu to set FEC (Flash Exposure Compensation) and 1st/ 2nd Curtain Sync. The 430EX (original), 550EX & 580EX (classic), MR-14EX (classic) & MT-24EX. Lack compatibility with the in camera flash menu. You can only set FEC (Flash Exposure Compensation) from the in camera flash menu. All other settings must be set from on the Speedlite’s LCD screen itself. Settings grayed out or missing cannot be set from the camera’s menu screen with older speedlites.
